## Abstract Lithium and magnesium enolates of cyclohexanone undergo palladium‐catalyzed allylic alkylations under mild conditions. Diastereoselectivity and enantioselectivity are observed when the diphenyl‐ and dimethyl‐substituted allylic substrates **1a** and **1b** are reacted with cyclohexanone

The generation of quatenary chiral centers through catalytic asymmetric alkylation of ketone enolates has been the subject of investigation in recent years. [1] The palladiumcatalyzed asymmetric allylic alkylation (AAA) of prochiral nucleophiles represents one such strategy for the creation of quate
