The reaction of himachalol with m-chloroperoxybenzoic acid afforded a rearrangement product, the structure of which was deduced by 2D NMR analysis to be 3α,4α-epoxyhimachalane-2α,7α-diol. The recently proposed 1H NMR assignments for himachalol have been revised, based on the analysis of 2D COSY, DEPT, HETCOR and NOE experiments.
喜马曲洛与间氯过氧苯甲酸的反应产生了重排产物,通过二维核磁共振分析推断其结构为3α,4α-环氧喜马曲烷-2α,7α-二醇。根据对二维COSY、DEPT、HETCOR和NOE实验的分析,对最近提出的喜马曲洛的1H NMR分配进行了修订。
