Reaction Steps

Methyl lithocholate is dissolved in methylene chloride, and β-methoxyethoxymethyl chloride and diisopropylethylamine are added. The mixture is stirred for four hours, ether added and washed with water. After drying the solvents are evaporated, the residue dissolved in toluene and the 24-ester group reduced to the 24-alcohol group with Vitride. The 24-alcohol then is oxidized with chromium trioxide-pyridine and the 3α-(β-methoxyethoxymethoxy)-5β-cholane-24-aldehyde obtained.
