  The transformation of schizandrin (I) into gomisin A (II) was accomplished by use of a combination of biotransformation and chemical reactions. The biotransformation, microbial O-demethylation of I by Cuntiinghamella echinulata var. elegans (ATCC 9245) produced two novel metabolites [3-norschizandrin (IV) and 2-norschizandrin (VI)] and two known metabolites [gomisin T (III) and 13-norschizandrin (V)]. Among those metabolites, compound III was derived to II by the O-demethylation with a Lewis acid in the presence of an acid scavenger, followed by methylenation.

  通过生物转化和化学反应相结合的方法，将五味子异黄酮（I）转化为戈米辛 A（II）。Cuntiinghamella echinulata var. elegans (ATCC 9245) 对 I 进行生物转化和微生物 O-去甲基化后，产生了两种新型代谢物[3-去甲五味子素（IV）和 2-去甲五味子素（VI）]和两种已知代谢物[五味子素 T（III）和 13-去甲五味子素（V）]。在这些代谢物中，化合物 III 是在有酸清除剂存在的情况下通过路易斯酸的 O-去甲基化反应生成 II 的，然后再进行甲基化反应。

• Regio- and stereoselective 12-O-demethylation of schizandrin into gomisin T, an important intermediate to gomisin A, by Mortierella sp. (TM-I1104)

  A strain TM-11104 identified as Mortierella sp. was discovered from soil as the most efficient fungus, which converted schizandrin into gomisin T in 91% regioselectivity by microbial 12-O-demethylation. Under optimum conditions, the yield of gomisin T reached around 80%. The faculty of 12-O-demethylation was specific on (+)-schizandrin (natural form) and the optical purity of gomisin T converted from (+)-schizandrin was 96% ee. (c) 2005 Elsevier Ltd.
