transformations. Advances and setbacks are reported in regard to the asymmetric total synthesis of the fungal metabolite curvicollide C relying on a synthetic strategy that exploits non-aldol stereotriads as chiral building blocks. A catalytic asymmetric Gosteli–Claisen rearrangement, a two-step aldehyde-to-alkyne-homologation, and a Julia–Kocienski olefination served as key C/C-connecting transformations.
摘要 据报道,真菌代谢产物curcollcollide C的不对称总合成方面存在进步和挫折,该合成依赖于利用非醛醇立体三联体作为手性结构单元的合成策略。催化的不对称Gosteli-Claisen重排,两步醛基至炔烃同构反应和Julia-Kocienski烯烃化反应是关键的C / C连接转化。 据报道,真菌代谢产物curcollcollide C的不对称总合成方面存在进步和挫折,该合成依赖于利用非醛醇立体三联体作为手性结构单元的合成策略。催化的不对称Gosteli-Claisen重排,两步醛基至炔烃同构反应和Julia-Kocienski烯烃化反应是关键的C / C连接转化。
