A Convenient and Effective Method for Synthesizing β‐Amino‐α,β‐Unsaturated Esters and Ketones

Abstract

Abstract A convenient and effective method for the preparation of β‐amino‐α,β‐unsaturated esters and ketones has been developed through silica gel‐catalyzed and solvent‐free reactions of β‐dicarbonylic compounds with ammonia and primary amines.
