In order to elucidate the absolute configuration of C-15 in natural hyptol, methyl (15S)-12,16-dihydroxy-8,11,13-abietatrien-18-oate and its (15R)-epimer were transformed into (15S)-12,16-epoxy-11,14-dihydroxy-8,11,13-abietatrien-7-one (1a) and its (15R)-epimer (1b), respectively. The synthetic 1a w as identical to natural hyptol. Thus, the stereochemistry of C-15 in the natural compound was conclusively
为了阐明天然hyptol中C-15的绝对构型,将甲基(15S)-12,16-dihydroxy-8,11,13-abietatrien-18-oate及其(15R)-差向异构体转化为(15S) -12,16-epoxy-11,14-dihydroxy-8,11,13-abietatrien-7-one (1a) 及其 (15R)-差向异构体 (1b)。合成的1a与天然hyptol相同。因此,天然化合物中 C-15 的立体化学最终被指定为 S-构型。
