  • Selective enzymatic esterification and solvolysis of epimeric vitamin D analog and separation of the epimers
    Patent number: 8129173
    Abstract: Provided is a method of selectively enzymatically esterifying or selectively enzymatically solvolyzing epimers of analogs of vitamin D having a stereogenic center at C-24 that has a free or esterified OH group. The metod can be used, for example, for separating mixed epimers of the vitamin D analog.
