palladium-catalyzed cross-coupling of 2-alkylaziridines with alkenylboronic acids to give homoallylamines is presented. The reaction is highly regioselective and stereospecific and provides convenient access to enantioenriched amines with 1,1-disubstituted, 1,2-disubstituted, and trisubstituted alkenes. The modular synthesis of a 2,5-disubstituted pyrrolidine natural product was completed in three steps
提出了钯催化的2-烷基氮丙啶与烯基硼酸的交叉偶联以得到高烯丙基胺。该反应具有很高的区域选择性和立体选择性,可方便地获得带有1,1-二取代,1,2-二取代和三取代烯烃的对映体富集的胺。2,5-二取代的吡咯烷天然产物的模块合成分三个步骤完成,总产率为67%。
