describe the stereoselective synthesis of 4α-bromo-5α-cholestan-3β-ol, 21-nor-5α-cholestan-3β-ol, 27-nor-5α-cholestan-3β-ol and 21,27-bisnor-5α-cholestan-3β-ol. In order to clarify the in vivometabolism of cholesterol, these compounds have been used for feeding experiments in Caenorhabditis elegans. Our preliminary results provide important insights into the metabolism of cholesterol in worms.
