Procedure
0.37 g (10 mmol) of sodium borohydride was added portionwise with cooling to the solution of 3.7 g (10 mmol) of cerium trichloride and 2.0 g (10 mmol) of 3-methyl-5-(1,2,2-trimethylbicyclo[3.1.0]hex-3-yl)pent-3-en-2-one in 25 ml of methanol. After 5 more minutes water was added and the mixture extracted with diethyl ether, dried (MgSO4) and evaporated in vacuo. Purification by flash chromatography on silica gel (eluent: hexane/MTBE 9:1) gave 1.3 g (58% yield) of 3-methyl-5-(1,2,2-trimethylbicyclo[3.1.0]hex-3-yl)pent-3-en-2-ol.
