Abstract
The transformation of schizandrin (I) into gomisin A (TI) was accompli shed by use of a combination of biotransformation and chemical reactio ns. The biotransformation, microbial O-demethylation of I by Cunningha mella Echinulata var. elegans (ATCC 9245) produced two novel metabolit es [3-norschizandrin (IV) and 2-norschizandrin (VI)] and two known met abolites [gomisin T (III) and 13-norschizandrin (V)]. Among those meta bolites, compound III was derived to II by the O-demethylation with a Lewis acid in the presence of an acid scavenger, followed by methylena tion.
