Abstract

Enantioseletive radical-mediated allylation using chiral Lewis acids generated from sulfonamides is described. Asymmetric allylation took place in 54% enantiomeric excess to form a chiral quaternary carbon center with R configuration. The present reaction proceeded equally well with a substoichiometric amount of a chiral Lewis acid as with a stoichiometric amount. (C) 1998 Elsevier Science Ltd. All rights reserved.
