The glucosylated monoterpenoids (–)-rhodioloside A and (–)-rhodioloside D from the roseroot (Rhodiola rosea) have been synthesized for the first time. Glucosylation with tetrapivaloylglucosyl bromide proved superior to the use of tetraacetylglucosyl bromide or glucosyl iodides. Acid-catalyzed cyclization of a homoglycidol-type geraniol derivative afforded the monoterpenoid tetrahydrofuran (+)-sachalinol
首次合成了来自蔷薇根(Rhodiola rosea)的葡萄糖基化单萜(-)-红景天苷A和(-)-红景天苷D。用四新戊酰葡糖基溴进行葡糖基化证明优于使用四乙酰葡糖基溴或葡糖基碘。高缩水甘油型香叶醇衍生物的酸催化环化得到来自红景天的单萜类四氢呋喃 (+)-sachalinol C。(+)-sachalinol C 的绝对构型需要修改。还获得了 (-)-Sachalinol A 和 (-)-sachalinol B。
