Abstract:
In this paper, a series of new substituted-5-pyrazolones were first synthesized, then formulated by the Vilsmeier–Haack reaction to obtain substituted-4-carbaldehyde-5-pyrazolones. In the final step, when urea was reacted with formulated pyrazolones, we found that, instead of the C=N bond in azomethine form, the compounds tautomerized to form a series of novel pyrazole-4-ylidenemethylurea structures. The structures of these compounds were elucidated by FTIR, 1H, 13C NMR, LC-MS/MS, and elemental analysis methods. The cytotoxic and antioxidant effects of substituted 5-pyrazolones and their pyrazolone-urea derivatives were investigated in metastatic A431 and noncancerous HaCaT human keratinocytes by a mitochondrial activity test. The effects of the compounds on the migration of cancerous and noncancerous cell lines were investigated by using a cell scratch assay. The General Linear Model, Statistical Package for Social Sciences (SPSS v26) was used to determine if there was a statistically significant difference between the control and the treatment groups. Four of the nine compounds showed an antioxidant effect. All 5-pyrazolone-urea compounds showed higher toxicity (p < 0.05) in cancerous A431 cells compared to noncancerous cells at all time points. All compounds also showed a biphasic hormetic effect. Four of the nine compounds inhibited cell migration.

Abstract:
AbstractPyrazolone is a five membered lactam ring, containing two nitrogen and one ketonic group in its structure. Pyrazalone's possesses anti-microbial, anti-fungal, antioxidant, anti-inflammatory, cytotoxicity, analgesic, anti-pyretic and anti-depressant activities. They also serve as precursors for dyes, pigments, pesticides, and chelating agents. Generally, the condensation of hydrazines with β-ketoester compounds is the classical method for the synthesis of pyrazolones, followed by reaction with various benzaldehyde derivatives. It is an exciting area of pharmaceutical chemistry to research the biological evaluation of pyrazolone derivatives. This review article provides information about different synthetic schemes and biological activities of various pyrazolone derivatives.KeywordsPyrazolone, Knorr condensation, Phenyl hydrazine, Ethyl Acetoacetate, Biological Activity.

Good regioselectivity for the isomeric structures was achieved by the reaction of isoxazole-styrene and azomethine imine in different solvents and temperatures. The developed method was extended for the synthesis of tri-substituted dinitrogen-fused pyrazolones by using a 1,6-Michael addition reaction. Furthermore, the isoxazole moiety was converted into a carboxylic acid as a model study via ring opening.

Abstract:
Nitrogen-containing heterocyclic compounds are very important to the pharmaceutical and agrochemical industries, among others. Over the past few years, the Beauchemin group has been exploring reactivity of N-substituted isocyanates and as part of this has developed a metal-free alkene aminocarbonylation process relying on imino-isocyanates to form azomethine imines. The azomethine imines formed are interesting since they contain a cyclic β-aminocarbonyl motif. Catalysis of this reaction using basic additives allowed milder reaction conditions with electron-rich C=C bonds such as enol ethers. Efforts have also been made towards the derivatization of these azomethine imines into useful products. It was discovered that upon reduction and aromatization of azomethine imines, pyrazolones could be obtained. This is providing a novel modular approach to these compounds, which have relevance in pharmaceuticals and agrochemicals. This reactivity was extended to include imino-isothiocyanates.

No primeiro relatamos nossos esforços visando descrever a primeira síntese total da (+)-Napalilactona, um nor-sesquiterpeno clorado extraído do coral Lemnalia africana. Essa substância marinha possui quatro centros estereogênicos consecutivos em sua estrutura, dois deles quaternários, sendo que um destes centros quaternários pertence também a um anel espiro. A estratégia sintética utilizou a (S)-Carvona como material de partida, de modo que foi possível, através do centro pré-existente no monoterpeno de partida, gerar o primeiro centro existente no produto natural. A partir deste centro, utilizando metodologias já bem estabelecidas na literatura, foi possível induzir a formação de dois dos três centros restantes, de modo que 78% do esqueleto carbônico do produto natural foi construído em um total de 10 etapas, com um rendimento global de 3%. Na segunda parte desse trabalho relatamos os resultados obtidos em um estudo metodológico envolvendo a reação entre a aminoguanidinina, um bis-nucleófilo polinitrogenado, e adutos de Morita-Baylis-Hillman (MBH) sililados e acetilados. Frente aos adutos de MBH sililados, as reações com a aminoguanidina conduziram, através de um processo tandem, à formação de uma mistura diastereoisomérica de pirazolidinonas sililadas em excelentes rendimentos, sendo que o diastereoisomero syn é o favorecido em todos os casos. A diastereosseletividade dessa reação variou de 2:1 a 7:1 (syn:anti). Quando investigamos o comportamento da aminoguanidina frente aos adutos de MBH acetilados, utilizando como solvente a acetonitrila, as reações com a aminoguanidina conduziram, também através de um processo tandem, à formação exclusiva de pirazolidinonas benzilidênicas, quando um aduto oriundo de um aldeído alifático ou oriundo de um aldeído aromático substituído com grupos doadores de elétrons foram utilizados. No entanto, frente a adutos oriundos de aldeídos aromáticos com grupos retiradores de elétrons, foi observada uma tendência à formação de pirazolonas, que são regioisomeros das pirazolidinonas previamente obtidas. Estes dados indicaram que, sob estas condições, a natureza do grupo substituinte rege a seletividade destas reações. Mais tarde, observou-se que, ao submetermos as pirazolidinonas a uma solução de 2 equivalentes de K2CO3 em metanol, estas poderiam ser completamente convertidas às respectivas pirazolonas. Mostrando a influência da natureza do solvente nestas transformações químicas<br>Abstract: This work is composed by two chapters. In the first one we disclosed our efforts towards the first total synthesis of (+)-Napalilactone, a chlorinated nor-sesquiterpene isolated from the coral Lemnalia africana. This marine natural compound has four consecutive stereogenic centers in their structure, two of them quaternaries. One of these quaternary centers belonging to a spiro ring. Our synthetic strategy started from commercially available (S)-carvone. The asymmetric center presented in this monoterpene was used to induce the first stereogenic center exhibited by the natural product. This task was accomplished by employing a sequence of well-established synthetic metodologies. This stereogenic center has induced the formation of two of the remaining three estereogenic centers. So that 78% of the carbon skeleton of the natural product has been built in a total of 10 steps with an overall yield of 3%. In the second part of this work we described the results of a methodological study envolving the reaction between aminoguanidinine, a polynitrogenated bis-nucleophile, and silylated and acetylated Morita-Baylis-Hillman adducts (MBH). The reaction of aminoguanidine with silylated MBH adducts gave, through a tandem process, a diastereoisomeric mixture of silylated pyrazolidinones in excellent yields, in which the syn diastereoisomer is favored in all cases. The diastereoselectivity of theses reactions ranged from 2:1 to 7:1 (syn:anti). When we investigated the reaction of aminoguanidine with acetylated aliphatic and eletron rich aromatic MBH adducts, using acetonitrile as solvent, the reaction afforded exclusively benzylidenic pyrazolidinones. However, when we investigated the reaction with acetylated eletron-poor aromatic MBH adducts, we observed the formation almost exclusively of pyrazolones, which are regioisomers of the previously obtained pyrazolidinones. These data indicated that under these conditions, the nature of the substituent group governed the selectivity of these reactions. Later, it was observed that by subjecting the pyrazolidinones to a solution of 2 equivalents of K2CO3 in methanol, they were completely converted to the corresponding pyrazolones, showing the influence of the nature of the solvent in these chemical transformations<br>Mestrado<br>Quimica Inorganica<br>Mestre em Química

Abstract:
L’organocatalyse permet l’activation de réactions chimiques diverses et représente une méthode complémentaire à la catalyse métallique ou à la catalyse par les enzymes. Cette stratégie peut être moins toxique et relativement plus accessible, en plus d’être fréquemment économique et écologique. En induisant une intramolécularité temporaire, il est possible de surmonter les pénalités entropiques inhérentes aux réactions intermoléculaires. Les travaux effectués par le groupe de recherche du Pr. Beauchemin ont jusqu’à date permis d’actualiser et d’améliorer des réactions d’hydroamination, d’hydratation d’amino nitriles et d’hydrolyse d’amides organophosphoniques grâce à l’organocatalyse aux aldéhydes simples. Dans cette optique, cette thèse étudie l’application de cette méthodologie dans des réactions d’hydrolyse. Dans un premier temps, les paramètres réactionnels favorisant l’hydrolyse d’α-amino esters furent investigués. Les problèmes de labilité de divers substrats en milieu aqueux furent abordés, de même que les difficultés à effectuer un « turnover » catalytique efficace. Dans un deuxième temps, la mono-hydrolyse de 1-amino diester phosphonique fut étudiée. Les esters d’acide 1-amino phosphoniques suscitent un intérêt en raison de leurs bioactivités diverses, notamment comme analogues d’acides aminés capables d’interactions biologiques avantageuses. Il fut possible d’optimiser plusieurs conditions réactionnelles, de même que d’étendre la portée de cette méthode à la synthèse de dérivés portant des groupements alkyles. Sur un autre ordre d’idées, les hétérocycles azotés font preuve de bioactivités importantes et variées. Conséquemment, leur emploi dans les domaines pharmaceutique et agrochimique est incontournable. Les cycles de type pyrazolone sont particulièrement présents dans des composés pharmaceutiques et dans des insecticides et des herbicides, tandis que les triazolium-olates présentes des activités biologiques intéressantes. Il devient ainsi essentiel de développer des voies polyvalentes, efficaces, peu dispendieuses et plus vertes pour leur synthèse. Des travaux antérieurs du groupe Beauchemin ont élaboré la génération in situ d’isocyanates et d’isothiocyanates N-substitués, des intermédiaires rares dans la littérature. Ils furent utilisés dans des réactions de cycloaddition avec des alcènes et des imines, pour former des azométhine imines. La deuxième partie de cette thèse s’intéresse à la dérivation de ces azométhine imines en dérivés de pyrazolone et en triazolium-olates grâce à une réaction d’isomérisation. Cette approche permet une déconnexion novatrice pour synthétiser directement des hétérocycles riches en azote complexes. L’optimisation de cette réaction fut mise au point et sa portée fut étudiée. Cette méthode s’avère peu dispendieuse, n’emploie aucun catalyseur métallique, ne requière pas de préfonctionnalisation et ne génère pas de sous-produits. Finalement, l’application de cette isomérisation à la résolution cinétique des azométhines imines fut tentée.
