โœฆ Synopsis

An easy and high yielding transformation of epoxyketones and phenyl substituted epoxides to trans olefins in a convergent diastereoselective process is reported. The method was applied to the selective C-25 hydroxy-functionalisation of 3-keto-D 4 -cholestan-3-one, a key intermediate for the synthesis of C-25 hydroxy vitamin D 3 .

Recent investigations have shown iron pentacarbonyl [Fe(CO)5] to be a useful reagent for effecting a variety of synthetic transformations.1 Non-polar solvents such as ethers have generally been employed for these reactions. In several cases, it has been demonstrated that reactions which do not take
