A total synthesis of both diastereomers of the originally proposed structure for streptophenazine A (1) has been achieved. However, both synthetic compounds are different from the natural product. Re-examination of NMR data reported for streptophenazine A and a concise total synthesis of both diastereomers of 17 (17a and 17b) led to the structural revision of streptophenazine A to 17b. Asymmetric synthesis
已完全合成了链霉菌素A(1)最初提出的结构的两种非对映异构体。但是,两种合成化合物均不同于天然产物。报告的链脲吩嗪A的NMR数据的重新检查以及17个非对映异构体(17a和17b)的简明全合成导致链脲吩嗪A的结构修订为17b。还进行了(-)-链霉吩嗪A的不对称合成,其绝对构型确定为1 'S,2'R。
