Abstract
The direct, high-yield oxyfunctionalization of the side-chain C-25 of 5α-cholestan-3-one, 3β-acetoxy-5α-cholestane, and 5α,6β-Br 2 -3β-acetoxycholestane as well as of the vitamin D 3 -derived Windaus-Grundmann ketone has been achieved under mild conditions employing either dimethyldioxirane or its trifluoromethyl analogue
