concise and highly stereoselective total synthesis of manzacidin B and its congeners has been developed following chelation-controlled syn-epoxidation and Lewis acid catalyzed intramolecular regioselective epoxide ring opening to generate the quarternary amine center. Elaboration of the triol moiety to the target molecule was achieved in good overall yield, representing practical total syntheses of
简明和manzacidin B的高度立体选择性全合成和其同源物已经被开发以下螯合控制顺环氧化和路易斯酸催化的分子内区域选择性环氧化物开环,以生成季胺中心。以良好的总收率实现了三醇部分与目标分子的精制,代表了曼杂酸B及其同系物的实际总合成。根据XRD,NMR和分析数据,证实了天然的山梨酸B((4 R,5 R,6 R)-6)的正确结构。
