Phosphane-mediated cyclizations between α-keto nitriles and methylidenemalononitriles, producing highly functionalized cyclopropanes in good to excellent yields, are reported. The presence of strongly electron-withdrawing cyano groups directly bound to the ketone carbonyl groups is believed to play a critical role in these transformations.
据报道,α-酮腈和亚甲基丙二腈之间的磷烷介导的环化以良好到极好的产率生产高度官能化的环丙烷。直接与酮羰基结合的强吸电子氰基的存在被认为在这些转化中起关键作用。
