Reaction Steps

To a vigorously stirred solution of 1,3,3,5,5-pentamethylcyclohexanol (3-13) (3.0 g, 17.65 mmol) in acetonitrile (20 ml) fuming HNO3 (6ml) was added dropwise, keeping temperature below 45° C. The resulting mixture was stirred at -50° C. for 6 h, then it was cooled, poured into water (30 ml) ana neutralised with aqueous NH3. Aqueous phase was extracted with ether (3*30 ml). The combined ether phases were washed with saline (30 ml), then dried over MgSO4, filtered and evaporated. The crude product was crystallised from cold acetonitrile to give 223 g (60%) of 14-2 as a white crystals, m.p. 110° C.
