This natural product contains a novel and unique 11b,12,13,14,15,16-hexahydroazepino[4',5':2,3]indolo[1,2-c]quinazoline ring system that has not previously been synthesized. We have synthesized 8-desbromohinckdentine A from a 2-aryl indole by first preparing the quaternary center of the natural product and then building the seven-membered lactam and dihydropyrimidine rings onto this intermediate to form
Hinckdentine A 是一种从苔藓虫 Hincksinoflustra denticulate 中分离出来的生物碱。这种天然产物含有一种新颖独特的 11b,12,13,14,15,16-hexahydroazepino[4',5':2,3]indolo[1,2-c] 喹唑啉环系统,该系统以前从未合成过。我们已经从 2-芳基吲哚合成了 8-desbromohinckdentine A,首先制备天然产物的季中心,然后在该中间体上构建七元内酰胺和二氢嘧啶环以形成 hinckdentine A 的框架。
