The palladium-catalyzed C(sp2)–H functionalization of bromoaryl aldonitrones leading to benzocyclobutenone-derived ketonitrones is described. This method allows for the preparation of a wide range of strained, four-membered ketonitrones with broad functional group tolerance. Downstream transformations of the formed products were readily demonstrated, illustrating the synthetic utility of the obtained
描述了溴芳基醛硝酮的钯催化 C(sp 2 )–H 官能化,生成苯并环丁酮衍生的酮硝酮。该方法可以制备各种具有广泛官能团耐受性的四元酮硝酮。所形成的产物的下游转化很容易被证明,说明了所获得的苯并环丁酮衍生的硝酮在构建多环含氮支架方面的合成效用。
