実験手順
Propionaldehyde (6.4 g) in acetonitrile (50 mL) was added over 30 minutes to a solution of cis/trans ethyl 4-{[(1,1-dimethylethyl)(dimethyl)silyl]oxy}cyclohexanecarboxylate (D1, 25.2 g), bismuth tribromide (4.4 g) and triethylsilane (17.5 mL) in acetonitrile (300 mL) and the mixture was stirred for a further 1.5 hours. The solvent was partially removed then the residue was treated with ethyl acetate and saturated sodium bicarbonate solution. The organic layer was separated, washed with brine, dried with anhydrous sodium sulphate and the solvent was removed to give the title compounds contaminated with silicone residues (39.1 g).
