The absolute stereochemistry of rhodiolosides A-D (1-4), four monoterpene glycosides from the roots of Rhodiola rosea, and their aglycones, rhodiolol A (5), (-)-rosiridol (6) and sachalinol A (7), were reinvestigated. It was found that the absolute configurations of C-4 in these compounds, previously assigned to be 4-R, should be revised to 4-S.
重新研究了红景天苷AD(1-4),玫瑰红景天根中的四个单萜糖苷以及它们的糖苷配基,Rhodiololol A(5),(-)-rosiridol(6)和sachalinol A(7)的绝对立体化学。已经发现,这些化合物中的C-4的绝对构型(先前指定为4-R)应修改为4-S。
