Five muurolane (1–5), one nor-seco-muurolane (6) and one nor-muurolane (7) sesquiterpene natural products recently reported from Cupressus bakeri have been obtained by chemical synthesis together with the unnatural 7-epimeric amorphane analogues of four of these sesquiterpenes (15, 16, 18 and 19). The conversion of sesquiterpene allylic tertiary alcohols 1, 2, 15 and 16 into regioisomeric sesquiterpene
5片穆罗拉尼(1-5),1片正癸二酸-穆罗拉尼(6)和1片正-穆罗拉尼(7)倍半萜最近通过化学合成获得了来自柏木(Cupressus bakeri)的天然产物,以及其中四个的非天然7-表异构体a啶烷类似物。倍半萜(15,16,18和19)。倍半萜烯丙基的转化叔醇 1,2,15和16为区域异构体倍半萜二烯3-5和17-20进行了研究在体外通过核磁共振 以及这种脱水的机制及其与血脂来源的相关性 倍半萜讨论了已报告为天然产物的二烯(例如3-5)。
