Organocatalysis [1] has expanded widely within the last few years, since the rediscovery of the proline-catalyzed aldol reaction. [2] Since then, several different methods, such as fluorination, [3] chlorination, [4] bromination, [5] sulfenylation, [6] amination, [7] and Mannich reactions, [8] have

## Abstract The first example of an organocatalytic asymmetric Michael addition of aldehydes to α,β‐unsaturated thiol esters promoted by chiral diphenylprolinol silyl ether is presented. The reaction occurs with good yields, diastereoselectivity and excellent enantioselectivity.
