A direct, highly enantioselective alkylation of arylacetic acids via enediolates using a readily available chiral lithium amide as a stereodirecting reagent has been developed. This approach circumvents the traditional attachment and removal of chiralauxiliaries used currently for this type of transformation. The protocol is operationally simple, and the chiral reagent is readily recoverable.
