摘要

A photomediated protocolgiving facile access to substituted & beta;-lactamand & beta;-lactones is presented. The method realizes, for the firsttime, the use of the Zimmerman-O'Connell-Griffin(ZOG) rearrangement in [2 + 2] cycloaddition. Products are obtainedin high yield with excellent diastereoselectivity under visible lightirradiation and under mild reaction conditions.
