On the C-25 Chirality of 26-Hydroxycholesterol

The stereospecific synthesis of (25S)-26-hydroxycholesterol with a chiral synthon derived from (S)-(+)-3-hydroxy-2-methylpropanoic acid is described and the Cotton effects of the CD spectra were found not to be a general means for distinguishing epimers of monohydric secondary alcohols or for distinguishing epimers in which the chiral center is in the α position to the primary alcoholic function.
