Synthesis of Prolinal Dithioacetals as Catalysts for the Highly Stereoselective Michael Addition of Ketones and Aldehydes to beta-Nitrostyrenes.

Tanmay Mandal1, Cong-Gui Zhao.   

Abstract

Catalytic highly enantioselective (up to >99% ee) and diastereoselective (up to 99% de) direct Michael addition of ketones and aldehydes to beta-nitrostyrenes have been achieved with readily accessible and highly tunable prolinal dithioacetal catalysts.
