Longipinene on exposure to acids rapidly rearranges to furnish α - and β-himachalenes, longifolene and isolongifolene. Longipinene epoxide, under acid catalysis, gives several products resulting from fragmentation and Wagner-Meerweinrearrangement. All products have been fully characterised. Formation of isocentdarol in this reaction requires revision of its stereochemistry at the centre carrying tertiary
