The reaction of (+)-2α-hydroxy-10β-pinan-3-one (1) with acetic anhydride afforded (+)-2α-acetoxy-10β-pinan-3-one (2), (−)-carvone (3), (−)-4α-acetoxy-10α-pinan-3-one (4), (+)-4β-acetoxy-10β-pinan-3-one (5), and (−)-4β-acetoxy-10α-pinan-3-one (6). The three products, 4, 5, and 6, were newly identified on the basis of a combination of chemical and physico-chemical methods. By examination using the 14C-labelled

Oxidative dehydrogenation of vicinal diols of bornane and pinane type with chlorine dioxide in dimethylformamide has yielded alpha-hydroxyketones with high selectivity. 3 alpha-Hydroxy-10 beta-pinane-4-one has been prepared for the first time with yield of 63-65%; the product structure has been confirmed by X-ray diffraction studies.
