A convenient method for the synthesis of 10-methyl- 8,10-diazabicyclo[4.3.1]decane, possessing a novel diazabicyclic ring system, as an important synthetic organic chemistry building block was developed using octanedioic acid as a starting material. The key transformation in the 5-step synthesis sequence involved a reaction of dimethyl 2,7-dibromooctanoate with methylamine, which resulted in the formation
以辛二酸为起始原料,开发了一种合成 10-甲基-8,10-二氮杂双环 [4.3.1] 癸烷的简便方法,该方法具有一种新型二氮杂双环系统,是一种重要的有机合成化学结构单元。5 步合成序列中的关键转变涉及 2,7-二溴辛酸二甲酯与甲胺的反应,导致形成顺式 1-甲基氮杂-2,7-二羧酸二甲酯。后者在与苄胺加热下进一步转化为双环8-苄基-10-甲基-8,10-二氮杂双环[4.3.1]癸烷-7,9二酮。用氢化铝锂还原形成的双环二酮产生 8-苄基-10-甲基-8,10-二氮杂双环[4.3.1]癸烷,氢解有效产生目标产物。
