Abstract

Alkylation reactions of the benzyllithiums derived from enantiomerically pure 2-p-tolylsulfinyl alkylbenzenes have been carried out with excellent yields and high de. A lithiation- substitution sequence, stereochemically controlled by a remote sulfoxide, accounts for the experimental results.
