Full details of a stereocontrolled and convergent synthetic route to 9a-desmethoxymitomycin A (1) are reported. The target molecule possesses the parent tetrahydropyrrolo[1,2-a]indole ring system characteristic of the mitomycin family of antitumor agents. The synthesis was based on the diastereocontrolled addition of a fully elaborated cinnamylstannane to a pyrrolidine-based N-acyliminium ion as the
报告了9a-去甲氧基丝裂霉素A(1)的立体控制和聚合合成路线的完整细节。目标分子具有丝裂霉素家族抗肿瘤剂特征的母体四氢吡咯并[1,2- a ]吲哚环系统。合成是基于非关键性地将完全精制的肉桂基锡烷添加到吡咯烷基N-酰基亚胺离子作为关键的收敛步骤,这导致安装了C9和C9a立体异构中心。
