A chemoenzymatic, asymmetric total synthesis of the anti-biotic (R)-fridamycin E has been accomplished following a biocatalytic deracemization procotol. The key step comprises the construction of the chiral side-chain from a functionalized rac-2,2-disubstituted oxirane via a kinetic resolution/stereoinversion sequence without formation of the undesiredstereoisomer.

抗生素 (R)-弗里达霉素 E 的化学酶促不对称全合成已在生物催化去消旋化过程中完成。关键步骤包括通过动力学拆分/立体转化序列从官能化的外消旋-2,2-二取代环氧乙烷构建手性侧链,而不会形成不需要的立体异构体。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
