Two alternative approaches to the side-chain of psymberin (1), psymberic acid (5), have been developed starting from either racemic or enantiopure acetal 6. A five-step chemoenzymatic route provided the PMB-protected acid (S,S)-16 required for the coupling that should ultimately lead to the natural product 1. (© Wiley-VCH Verlag GmbH & Co.

已经从外消旋或对映纯缩醛 6 开始开发了 psymberin (1) 侧链的两种替代方法 psymberic acid (5)。五步化学酶促路线提供了 PMB 保护的酸 (S,S)-最终产生天然产物 1 的偶联所需的 16。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
