Etude de la catalyse vis à vis de la réaction de Mannich et élaboration de nouvelles structures via la réaction de Maillard–Hantzsch
MetadataShow full item record
In this manuscript we are interested in the development of multi-component reactions by studying the catalytic power of new catalysts on some of them: the Mannich reaction and synthesis of β- amino carbonyl compounds. In the first part ,we studied the effect of three catalysts, which are Silica-supported Antimony (III) chloride, the phenylboronicacid and Polyethylene glycol 600 on Mannich reaction which gave the β-amino Ketones with good yields in generel. In the second part, our research was focused on the develop the new structures via the cascade Maillard-Hantzsch , another class of heterocycles with very interesting biological and medicinal properties, using a phenylboronic acid as catalyst, which may have the advantage of being no-toxic, low-cost and easily work-up. The obtained yields are good to excellent.
