N-lithio-ethylenediamine as an isomerizing and dehydrogenating reagent has been further extended. It is useful for partial aromatization of cadinenic terpenes and for conversion of selenenic compounds to heteroannular diene, optical rotation of which throws light on the absolute configuration of the parent compound. It is also useful for smooth isomerization of fatty acid.
Khusol, a crystalline primary sesquiterpene alcohol, C15H24O, isolated from North Indian vetiver oil has been assigned the structure and absoluteconfiguration represented by I. It belongs to the antipodal group of cadinenic alcohols.
从印度北部香根草油中分离得到的Khusol(一种结晶的倍半萜烯醇,C 15 H 24 O)已被赋予I所示的结构和绝对构型。
