Visible light-mediated arylalkylation of allylic alcohols through concomitant 1,2-aryl migration

Abstract

A photocatalytic process for selective arylalkylation of allylic alcohols with α-bromo diethyl malonate has been developed. The reaction provided a straightforward approach to synthesize α-aryl-β-alkylated ketones via unique 1,2-aryl migration. The procedure is highlighted by its operational simplicity and mild reaction conditions.
