Abstract
An unexpected phosphine-catalyzed [3 + 2] annulation from electron-deficient allenes and substituted alkylidenemalononitriles was realized in which the allylic moiety of the substituted alkylidenemalononitriles served as the three carbon unit of the cyclopentenes instead of the electron-deficient allenes.
摘要
实现了一种意外的膦催化缺电子丙二烯与取代亚烷基丙二腈的[3+2]环化反应，其中取代亚烷基丙二腈的烯丙基部分作为环戊烯的三个碳单元，而不是缺电子丙二烯。
