A new method of synthesis of functionally substituted α-bromoallenes on the basis of 1,4-dibromobuta-1,2-diene has been developed. α-Bromoallenes are shown to react with nucleophilic reagents with allene-acetylene rearrangement thus affording high yields of functionalized acetylenic derivatives of hitherto unknown types. In contrast to this, the interaction of methyl 4-bromobuta-1,2-dienoate with amines
开发了一种新的合成方法,该方法以1,4-二溴丁烯-1,2-二烯为基础合成功能取代的α-溴丙二烯。已显示α-溴代烯与具有烯-乙炔重排的亲核试剂反应,因此提供了迄今未知类型的官能化炔属衍生物的高产率。与此相反,作为4-烯丙基系统的中心C原子上亲核加成的反应,发生了4-溴丁烯-1-二-二烯酸甲酯与胺的相互作用。
