alpha-hydroxy-17-ketones and 17 beta-hydroxy-16-ketones (3b and 4b, 6a and 7a, 6b and 7b, respectively). In addition, in these three last experiments, the 16 beta-17 beta-dihydroxy derivatives 5b, 8a, and 8b, respectively, were also isolated. The complete assignments of the 13C nuclear magnetic resonance spectra of these compounds are given.
将雌酮(1a)与玫瑰色链霉菌ATCC 13400一起温育产生3,16 alpha-dihydroxyestra-1,3,5(10)-trien-17-one(3a)和3,17 beta-dihydroxyestra-1,3的混合物,5(10)-三烯-16-一(4a)。3-甲氧基estra-1,3,5(10)-trien-17-one(1b),3-hydroxyestra-1,3,5(10),9(11)-tetraen-17-one(2a) ,和3-甲氧基estra-1,3,5(10),9(11)-tetraen-17-one(2b)与相同的微生物给出了16个α-羟基-17-酮和17个β-羟基的相应混合物-16-酮(分别为3b和4b,6a和7a,6b和7b)。另外,在这最后三个实验中,还分别分离了16个β-17β-二羟基衍生物5b,8a和8b。给出了这些化合物的13 C核磁共振谱的完整分配。
