Novel total syntheses of oxoaporphine alkaloids such as liriodenine, dicentrinone, cassameridine, lysicamine, oxoglaucine and O-methylmoschatoline were developed. The key step of these total syntheses is Cu-catalyzed conversion of 1-benzyl-3,4-dihydro-isoquinolines (1-Bn-DHIQs) to 1-benzoyl-isoquinolines (1-Bz-IQs) via tandem oxidation/aromatization. This novel Cu-catalyzed conversion has been studied
开发了新的全合成氧代阿泊啡生物碱,如马钱烯宁、二百曲宁、卡沙美啶、赖西胺、氧代月光碱和O-甲基莫沙托林。这些全合成的关键步骤是通过串联氧化/芳构化,铜催化将 1-苄基-3,4-二氢-异喹啉 (1-Bn-DHIQs) 转化为 1-苯甲酰基-异喹啉 (1-Bz-IQs)。这种新颖的铜催化转化已被详细研究,并成功用于构建 1-Bz-IQ 核心。
