Procedure

A mixture of 11.0 g (52 mmol) of 2-(1,2,2-trimethylbicyclo[3.1.0]hex-3-ylmethyl)-[1,3]-dioxolane, 80 ml of acetone, 40 ml of water, 1.5 ml of conc. hydrochloric acid and 10 g of silica gel was stirred at reflux for 4 hours. After filtration, the solution was diluted with diethyl ether, washed with water, dried (MgSO4) and evaporated in vacuo. Kugelrohr distillation of the residue gave 6.8 g (79% yield) of (1,2,2-trimethylbicyclo[3.1.0]hex-3-yl)ethanal.
