Total synthesis of debromoflustramines B and E has been accomplished by using a platinum-catalyzed addition reaction of o-aminophenylboronic acid with the allene and an intramolecular carbamoylketene–alkene [2 + 2] cycloaddition for the construction of the basic carbon framework of the target alkaloids as the key steps.
通过使用邻位氨基苯基硼酸与烯丙基的铂催化加成反应和分子内氨基甲酰乙烯酮-烯烃[2 + 2]环加成反应,可完成十溴氟乙胺B和E的全合成,从而构建目标生物碱的基本碳骨架作为关键步骤。
