A complementary dual carbonyl activation strategy for the synthesis of polycyclic alkaloids has been developed. Successful applications include the synthesis of tetracyclic alkaloids harmalanine and harmalacinine, pentacyclic indoloquinolizidine alkaloid nortetoyobyrine, and octacyclic β-carboline alkaloid peganumine A. The latter synthesis features a protecting-group-free assembly and an asymmetric
已经开发出用于合成多环生物碱的互补双羰基活化策略。成功的应用包括四环生物碱骆驼蓬菌素和骆驼蓬菌素、五环吲哚喹啉西啶生物碱去甲代拜林和八环β-咔啉生物碱peganumine A的合成。后者的合成具有无保护基组装和不对称二磺酰亚胺催化环化的特点。此外,还实现了 hirsutine、deplancheine、10-desbromoarborescidine A 和 oxindole 生物碱钩藤碱和异钩藤碱的正式合成。最终完成了小檗碱生物碱ilicifoline B的简捷合成。
