We have studied the remarkable dependence of the stereochemistry of the cyclization on the double bond geometry and of the effect of the bulkiness of the nucleophile on the regiochemistry of the palladium mediated cyclization of alkenes bearing aryl bromides and nucleophiles. In contrast, the cyclization of the acetylenic homologous substrates is not dependent on the nature of the nucleophile.
我们已经研究了环化的立体化学对双键几何的显着依赖性以及亲核试剂的大体积对钯介导的带有芳基溴化物和亲核试剂的烯烃介导的环化的区域化学的显着依赖性。相反,炔属同源底物的环化不取决于亲核试剂的性质。
