(15R)-11,16-Dihydroxy-12-methoxymethoxy-8,11,13-abietatrien-7-one and its (15S)-epimer prepared from a C-15 epimeric mixture of 12-methoxy-8,11,13-abietatrien-16-ol, were transformed into (15R)-6,11,12,14,16-pentahydroxy-5,8,11,13-abietatetraen-7-one and its (15S)-epimer; these were identical with natural (15R)-coleon C and (15S)-coleon C, respectively.
(15R)-11,16-二羟基-12-甲氧基甲氧基-8,11,13-abietatrien-7-one 及其 (15S)-差向异构体由 12-甲氧基-8,11,13 的 C-15 差向异构混合物制备-abietatrien-16-ol,被转化为 (15R)-6,11,12,14,16-pentahydroxy-5,8,11,13-abietatetraen-7-one 及其 (15S)-差向异构体;它们分别与天然 (15R)-coleon C 和 (15S)-coleon C 相同。
