This manuscript describes an enantioselective synthesis of the naturally occurring alkaloid citrinadin B. The synthetic effort revealed an anomaly in the original structural assignment that has led to the proposal of a stereochemical revision. This revision is consistent with the structures previously reported for a closely related family of alkaloids, PF1270A-C. The synthesis is convergent and employs
这份手稿描述了天然存在的生物碱 citrinadin B 的对映选择性合成。 合成工作揭示了原始结构分配中的异常,这导致了立体化学修订的提议。此修订版与先前报告的密切相关的生物碱家族 PF1270A-C 的结构一致。该合成是收敛的,并采用立体选择性分子间硝酮环化反应作为关键步骤。
