โœฆ Synopsis


Rearrangement of ally1 enol carbonates, prepared from ketones or aldehydes by trapping their enolates with ally1 chloroformate, to give e-ally1 ketones or aldehydes regioselectively is catalyzed by palladium-phosphine complexes under mild condtions.

## Abstract Palladiumโ€catalyzed asymmetric allylic alkylation of nonstabilized ketone enolates to generate quaternary centers has been achieved in excellent yield and enantioselectivity. Optimized conditions consist of performing the reaction in the presence of two equivalents of LDA as base, one e

## Abstract Lithium and magnesium enolates of cyclohexanone undergo palladiumโ€catalyzed allylic alkylations under mild conditions. Diastereoselectivity and enantioselectivity are observed when the diphenylโ€ and dimethylโ€substituted allylic substrates **1a** and **1b** are reacted with cyclohexanone
