Abstract

Oxy-Cope rearrangement of diastereomeric l, 5-hexadien-3-ols, new key intermediates for terpenoids pio-duction in industrial scale, were investigated in neat systems and solvent assisted systems. Various solvents affecting the selectivity of [3, 3]-shift were classified by means of NMR studies on hydroxyl proton exchange time.
