Tetrasubstituted Imidazoles

A high-yielding synthesis of 1,2,4,5-tetrasubstituted imidazoles is described, involving the reaction of 1,2-dicarbonyl compounds, aryl aldehydes, amines and ammonium acetate in the presence of a catalytic amount of glutamic acid under thermal, solvent-free conditions. The salient features of this protocol are aerobic conditions, a non-hazardous green catalyst, short reaction times and mild reaction conditions.

An efficient and environmentally benign protocol for the one-pot, three-component synthesis of 12-aryl-8,9,10,12-tetrahydro-benzo[a]xanthen-11-one derivatives by condensation of aryl aldehydes, 2-naphthol and dimedone using H4SiW12O40(SiWA) as a reusable catalyst with high catalytic activity was reported. The reaction was carried out at 100 ºC under solvent-free conditions within 15-40 min in 82-91% yield.

An efficient synthesis of alkyne-3-tetrazolyl-tetrazolo[1,5-a] quinolones via a one-pot isocyanide-based multicomponent reaction (IMCR) process: I-MCR Ugi-azide/SNAr/ring-chain azido tautomerization was performed under eco-friendly conditions. We report the one-pot synthesis of tris-heterocycles containing a tetrazolo[1,5-a] quinoline connected to a 1,5-disubstituted-tetrazole (1,5-DS-T). The synthesis of these compounds is of great interest in synthetic and medicinal chemistry because these heterocycles are considered privileged scaffolds and their preparation and evaluation may lead to the discovery of novel bioactive molecules.
