Abstract
AbstractHerein we report an ultrasound‐assisted zinc‐catalyzed solvent‐free process for the synthesis of enaminoketoesters from 1,3 dicarbonyl compounds, N, N‐Dimethylformamide dimethyl acetal (DMFDMA) and various amines with good to excellent yields. This methodology is very much applicable for primary aliphatic, aromatic and secondary alicyclic amines bearing different functional groups. The present work offers the following merits such as inexpensive reagents, one‐pot reaction, eco‐friendly and tolerance to different functional groups with short reaction time.
