  烯基膦酸酯通过 Horner-Wadsworth-Emmons 烯烃的烯化

  摘要：

  单取代和双取代的丙二烯 5 是通过从亚甲基双膦酸酯 1 和两个羰基化合物开始的连续霍纳-沃兹沃思-埃蒙斯烯化合成的。成功的关键是 KH 或 KH-18-crown-6 作为羟基烯基膦酸酯 4 的第二次 HWE 烯化的基础。

  Synthesis of allenes by double Horner–Wadsworth–Emmons reaction

  摘要：

  LDA treatment of aldehydes or ketone with alkenylphosphonates 2, prepared by Horner-Wadsworth-Emmons (HWE) reaction of methylenebisphosphonate I with aldehydes, afforded Baylis-Hillman reaction-type products 5 in high yields. HWE olefination of 5 with KH or KH-18-crown-6 as a base provided allenes in good yields. One-flask procedure was successfully developed starting from I to afford an allene in a reasonably good yield.

  Mono- and di-substituted allenes 5 were synthesized by successive Horner-Wadsworth-Emmons olefination starting from methylene-bisphosphonate 1 and two carbonyl compounds. The key to success is KH or KH-18-crown-6 as a base for the second HWE olefination of hydroxyalkenylphosphonates 4 .
