The first enantioselective total synthesis of (+)-coriandrone A and B, two bioactive natural products, has been achieved in 10 steps and 11 steps starting from commercially available methyl 2-hydroxy-4-methoxybenzoate. Key reactions include a Claison rearrangement, a Shi-type epoxidation–cyclization sequence and ortho-metallation of t-butylbenzamides with (S)-(−)-propylene oxide reaction.
从市售的 2-hydroxy-4-methoxybenzoate 甲酯开始,通过 10 个步骤和 11 个步骤,首次实现了 (+)-coriandrone A 和 B 这两种具有生物活性的天然产物的对映体选择性全合成。关键反应包括克莱森重排反应、Shi 型环氧化-环化顺序以及 t-丁基苯甲酰胺与 (S)-(-)- 环氧丙烷的正金属化反应。
