Base-promoted regiodivergent allylation of N-acylhydrazones with Morita–Baylis–Hillman carbonates by tuning the catalyst

Abstract

A regiodivergent allylation of N-acylhydrazones with Morita–Baylis–Hillman (MBH) carbonates has been developed, providing α- or γ-allylated products in excellent yields by using different catalysts. The nature of the base catalyst plays a pivotal role in controlling the reaction pathway, allowing regiospecific access to diverse allylic substituted target compounds from identical substrates.
