The synthesis of a number of mono- and difluorinated steroids with the potential to act as probes of the metabolism of cholesterol is described. 2α-Fluorocholestan-3-one 7, 4-fluorocholest-5-en-3-one 11 and 6-fluorocholest-4-en-3-one 12 were synthesised from the appropriate silyl enol ethers using 1-fluoropyridinium triflate, and subsequently reduced to the corresponding alcohols, 8, 13 and 14 respectively
