中文摘要：
在这个工作，在修改 allylic 衍生物和极的 1,1-dicyano-1,3-dienes 之间的催化磷化氢的环反应被学习了。在 PPh3 (20 mol%) 的催化作用，一[4+1 ] 环反应在一系列 1,1-dicyano-2,4-diaryl-1,3-dienes 和激活 ethoxycarbonyl 的 allylic 醋酸盐之间被认识到，生产 polysubstituted cyclopentenes 在对优秀收益谦虚。1,3-dienes 和 allylic 衍生物的取代者在环模式上有重要影响，这也被观察：在 PPh3 或 PBu3 (20 mol%) 的催化作用下面， regioselective [3+2 ] 环产品从不同地代替的底层被形成。
英文摘要：
in this work, the phosphine-catalyzed annulation reactions between modified allylic derivatives and polar 1,1-dicyano-1,3-dienes have been studied. In the catalysis of PPh3 （20 mol%）, a [4 ＋ 1 ] annulation reaction is realized between a series of l,l-dicyano-2,4-diaryl-1,3-dienes and ethoxycarbonyl-activated allylic acetate, producing polysubstituted cyclopentenes in modest to excellent yields. It is also observed that the substituents of both 1,3-dienes and allylic derivatives have a significant influence on the annulation mode： under the catalysis of PPh3 or PBu3 （20 mol%）, regioselective [3 ＋ 2] annulation products are formed from differently substituted substratcs.
