Pot, atom and step economic (PASE) synthesis of 5-monoalkylbarbiturates through domino aldol-Michael reaction

Jyoti Kalita, Subarna,Mecadon, Hormi,Deka, Dibakar Chandra

supporting information, p. 731 - 734 (2015/01/30)

A simple pot, atom and step economic (PASE) approach for the synthesis of 5-monoalkylbarbiturates by a one-pot reaction of barbituric acids, aldehydes, and ketones, involving a domino aldol-Michael reaction is described. The operational simplicity and cost effectiveness of this procedure makes it a sustainable strategy for the synthesis of 5-monoalkylbarbiturates.
