A photomediated protocol giving facile access to substituted β-lactam and β-lactones is presented. The method realizes, for the first time, the use of the Zimmerman-O'Connell-Griffin (ZOG) rearrangement in [2 + 2] cycloaddition. Products are obtained in high yield with excellent diastereoselectivity under visible light irradiation and under mild reaction conditions.
本文介绍了一种通过光介导的方法,可轻松获得取代的β-内酰胺和β-内酯。该方法首次实现了在[2 + 2]环加成反应中使用齐默尔曼-奥康奈尔-格里芬(ZOG)重排。在可见光照射和温和的反应条件下,产物以高收率和优异的非对映选择性得到。
