cyclization-carbonylation of 1,3-dienes is described. The reaction proceeds via an intramolecular nucleophilic addition on the diene to give an intermediate π-allyl palladium complex which is subsequently carbonylated to give either a overall 1,2- or 1,4-addition over the diene. By proper choice of reaction conditions control of the regiochemical outcome of the reaction was obtained.
描述了新的钯介导的1,3-二烯的串联环化-羰基化。反应通过在二烯上的分子内亲核加成进行,得到中间体π-烯丙基钯配合物,随后将其羰基化以在二烯上总体上进行1,2-或1,4-加成。通过反应条件的适当选择控制反应的区域化学结果的获得。
