Abstract:
The mechanism of the Paal–Knorr reaction was explored using quantum chemical methods. Hydronium ion catalysed hemialcohol pathway has been established as the preferred mechanistic route for the Paal–Knorr formation of furan, pyrrole and thiophene.

Abstract:
The detection of pyrrole rings in numerous organic compounds with various pharmacological activities, emphasizes its huge importance in medicinal chemistry. Thus, the synthesis of pyrroles continues to arouse interest and Paal-Knorr condensation is considered to be the main synthetic route. A significant advance has been made since the MW activation was introduced in the organic synthesis which can be confirmed with the rapid growth of the published papers on that topic. Microwave irradiation is gaining popularity since faster reaction time, higher yields, easier work-up and reduced energy inp

Abstract:
Ce travail décrit de nouvelles voies de synthèse d'hétérocycles phosphoniques. La première partie concerne l'étude de la formation d'indoles phosphoniques via un intermédiaire benzénique, convenablement substitué en vue d'une hétérocyclisation. Deux voies de synthèse ont retenu notre attention nous permettant de préparer des 3-phosphonoindoles porteurs d'une fonction amine, alkyle, aryle ou hydroxyle. La première voie fait appel à une réaction de couplage entre l'orthoiodonitrobenzène et un phosphonate α-fonctionnel, puis une hydrogénation du groupement nitro suivie de la réaction de cyclisati

Abstract:
Pyrroles are found in various natural products and in the chemical composition of certain drugs because of their interesting biological properties. Lipitor, Tolmetin and Amtolmetin are examples of drugs with 1,2,5-substituted pyrroles in their composition, in which biological activities have been certified. Moreover, pyrroles are used as precursors of semiconductor polymers, oligomers and dendrimers useful for the synthesis of electroluminescent materials used in devices, such as organic light-emitting diodes, field-effect transistors, solar and organic photovoltaic cells.
