Remote Asymmetric Induction in Michael Additions of Allylic Sulfones.
-A new pathway of remote asymmetric induction in Michael reactions involving allylic Ξ±-phenylsulfonyl carbanions in chiral donors is reported. The transmission of asymmetry is found to depend on the presence of an aromatic nucleus bound to the chiral center of the N-substituent in the donors. The change from phenyl to naphthyl improves the diastereocontrol of the reaction, whereas with cyclohexyl equal amounts of two diastereomers are formed.

## Abstract The mechanism of stereoselectivity has been elucidated for the formation of two stereogenic centers in the products of Michael addition to ethyl crotonate by lithiated Ξ±βanions of allylic sulfones bearing a remote chiral __N__βsubstituent. In order to single out reactive carbanion struc
