Visible light mediated regioselective 1,3-oxylallylation of aryl cyclopropanes under redox-neutral conditions†

Abstract

A photoredox catalysed 1,3-oxylallylation of aryl cyclopropanes was accomplished by reaction with carboxylic acids and allyl sulfones. The redox-neutral reaction proceeded in a highly regioselective manner under mild conditions with good functional group compatibility. Simple operation and successful application to the late-stage functionalization of several natural product and pharmaceutical molecule related carboxylic acids add extra merits to the current protocol.
