Procedure

1.52 g (3.3 mmol) of (2R,6RS,10RS)-2,6,10,14-tetramethyl-1-tosyloxy-2-pentadecanol were dissolved in 20 ml of ethanol. 2 ml of sodium hydroxide solution (50%) were then added and the mixture was stirred for 16 hours. Subsequently, 50 ml of water were added and the mixture was stirred up with HYFLO. The suspension was then filtered and washed with water. The residue was triturated with diethyl ether, dried over sodium sulphate, filtered and concentrated. There was obtained (2R,6RS,10RS)-1,2-epoxy-2,6,10,14-tetramethylpentadecane with [α]D20 =-0.21° (c=2% in CHCl3).
