Abstract

Abstract o-Allyloxyanisoles are selectively and easily deallylated by treatment with sec-or tert-butyllithium at low temperature. The reaction is proposed to proceed through a tandem intermolecular carbolithiation-β-elimination process, which can also be considered an SN 2′ attack of the organolithium on the allyl ether.
