Enantioselective Seleno‐Michael Addition Reactions Catalyzed by a Chiral Bifunctional N‐Heterocyclic Carbene with Noncovalent Activation

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(23)

Published: March 24, 2022

Abstract The Michael reaction is a conjugate addition and one of the most powerful methods with which to prepare functional molecules β‐stereogenic center. Despite its success in formation various asymmetric carbon–carbon carbon–heteroatom bonds, enantioselective seleno‐Michael remains essentially unexplored. We report here highly alkyl selenols enones. This method conveniently introduces Se atom an electron‐deficient double bond asymmetrically. A chiral bifunctional N‐heterocyclic carbene (NHC)/thiourea catalyst was developed as key ingredient that delivers β‐seleno ketones remarkable selectivity. new mode action support broad applications catalytic activation nucleophilic reactions.
