enantiospecific total syntheses of structurally diverse natural products such as machaeriol-D, Delta(8)-THC, Delta(9)-THC, epi-perrottetinene and their analogues. Synthesis of both natural products and their enantiomers has been achieved with high atom economy, in a protecting group free manner and in less than 6 steps, the longest linear sequence, in a very good overall yield starting from R-(+) and S-(-)-limonene
已经开发出一种简单的,高度非对映选择性的路易斯酸催化的环状烯丙基醇与间苯二酚衍生物的Friedel-Crafts偶联。该方法适用于结构多样的天然产物,如马卡儿酚-D,Delta(8)-THC,Delta(9)-THC,epi-perrottetinene及其类似物的对映体特异性全合成。天然产物及其对映异构体的合成均以高原子经济性,无保护基的方式,最长的线性序列少于6个步骤,从R-(+)和S-开始的非常好的总收率完成(-)-柠檬烯。
