    • Epimerization of 5 is so facile that purification on silica gel pretreated with triethylamine (2.5%, v/v) was sufficient to produce the cis isomer.

    • The C-4 S isomer (benzyl acetate) could be converted to diol 6 by hydrogenolysis, lactonization under Mitsunobu conditions, and reduction.
