Élaboration de nouvelles voies catalytiques vis-à-vis des RMCs type Biginelli et pseudo-Biginelli et Synthèse de nouvelles molécules tétrahydrobenzo[b]pyranes.

Abstract

The present work on the development of multicomponent reactions by studying the catalytic power of novel catalysts on multicomponent reactions giving 3,4-dihydropyrimidinones (Biginelli reaction) and tetrahydrobenzo [b] pyrans has not only allowed to to enrich these reactions by new catalytic pathways by using new catalysts such as sodium, strontium (II) and nickel or by ultrasonic activation, but also to expand the library of tetrahydro benzo[b] pyrans by synthesizing new molecules potentially biologically useful.
