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 1 H NMR assignments for himachalol have been revised, based on the analysis of 2D COSY, DEPT, HETCOR and NOE experiments.
