Acetates of Baylis-Hillman adducts derived from ethyl acrylate, methyl vinyl ketone, and acrylonitrile were coupled with allyltributylstannane using Pd(PPh3)4 or Pd(dba)2 as the catalyst at room temperature to afford the corresponding trisubstituted alka-1,5-dienes in good to high yields.
从乙基丙烯酸酯、甲基烯基酮和丙烯腈衍生的 Baylis-Hillman 加合物的醋酸盐与烯丙基四丁基锡在室温下使用 Pd(PPh3)4 或 Pd(dba)2 作为催化剂偶联,得到相应的三取代烯-1,5-二烯,产率良好至很高。
