Abstract

A general and efficient protocol for the Michael addition reactions of β-ketoesters in pure water has been developed. The reactions are successfully catalyzed by newly designed DMAP-related organocatalysts such as 4-(didecylamino) pyridine, and the desired Michael adducts are obtained in good to high yields
