The formal total synthesis of the antitubercular agent erogorgiaene was achieved in 12 steps by using a protecting group free strategy. The synthesis involves an enamine-mediated 1,4-addition, an aldol condensation, dehydrogenation, Wittig olefination, intramolecular Friedel–Crafts cyclization, TEMPO-BAIB-mediated oxidation, and Evans auxiliary based diastereoselective methylation.
通过使用无保护基团策略,通过 12 个步骤实现了抗结核剂 erogorgiaene 的正式全合成。该合成涉及烯胺介导的 1,4-加成、羟醛缩合、脱氢、Wittig 烯化、分子内 Friedel-Crafts 环化、TEMPO-BAIB 介导的氧化和基于 Evans 辅助的非对映选择性甲基化。
