Abstract
Zn(OAc)2•2H2O-catalyzed one-pot multicomponent reaction of Betti bases using β- naphthol, aldehydes, and amines, under neat conditions in moderate to excellent yields (68- 96%) is reported in this study. This synthetic protocol offers several advantages, such as operational simplicity, shorter reaction period, high yields, and easy work-up procedures.
Keywords: Betti base, zinc acetate dehydrate (Zn(OAc)2•2H2O), catalysis, multicomponent synthesis, β-naphthol, amines and solvent-free conditions.
