Abstract:

Photochemical reactions (λ > 300 nm) of N-(1-methylpyrimidin-2-one)-and N-(1,5-dimethyl-pyrimidin-2-one)pyridinium chlorides were studied in deoxygenated aqueous solution at various pH's. Only the former compound was found to be reactive under these conditions to give pyrimidine ring contraction photoproducts 1-methyl-4-imidazolin-2-one and 1-methyl-4-imidazolin-2-one-5-carboxyaldehyde, with pH-dependent chemical yields. The photochemical pyrimidine ring contraction reaction does not occur for other photochemically reactive pyrimidin-2-ones bearing 3-methylimidazolium-1,1,2,4-triazol-1-yl,

Chitosan, a chitin-derivative polysaccharide, known for its non-toxicity, biocompatibility and biodegradability, presents limited applications due to its low solubility in neutral or basic pH medium.

Quaternization occurs by introducing a quaternary ammonium moiety onto or outside the chitosan backbone, via chemical reactions with primary amino and hydroxyl groups, under vast experimental conditions.

The NMR measurements confirm chemical structure of the compound. Observation with polarsing optical microscopy evaluated that the compound shows fine multi-domains having fluidity. The lyotropic LC thus prepared displays smectic phase with layer structure.

Abstract:

Surfactants are self-assembled compounds that depend on their structure and electric charge can interact as monomer or micelle with other compounds (substrates). These interactions which may catalyze or inhibit the reaction rates are studied with pseudophase, cooperativity, and stoichiometric (classical) models. In this review, we discuss applying these models to study surfactant-substrate interactions and their effects on Diels-Alder, redox, photochemical, decomposition, enzymatic, isomerization, ligand exchange, radical, and nucleophilic reactions.

Abstract:

AbstractTransition-metal free reactions of diazo compounds with organoboron compounds provide some unique approaches for the formation of C–C, C–B and C–Si bonds. WithN-tosylhydrazones as the precursors for non-stabilized diazo compound, this type of reaction becomes practically useful in organic synthesis. Transition-metal-free synthetic methodologies for borylation,gem-diborylation,gem-silylborylation arylation, 2,2,2-trifluoroethylation andgem-difluorovinylation have been successfully developed.

Abstract:

The curiosity and attention that researchers have devoted to alkaloids are due to their bioactivities, structural diversity, and intriguing chemistry. Marine-derived macrocyclic alkaloids (MDMAs) are considered to be a potential source of drugs. Trabectedin, a tetrahydroisoquinoline derivative, has been approved for the treatment of metastatic soft tissue sarcoma and ovarian cancers. MDMAs displayed potent activities that enabled them to be used as anticancer, anti-invasion, antimalarial, antiplasmodial, and antimicrobial. This review presents the reported chemical structures, biological activ
