Selective enzymatic esterification and solvolysis of epimeric vitamin d analog and separation of the epimers |
abstract |
A method is provided for selectively esterifying an epimer of a vitamin D analog having a stereogenic center at C-24 with free or esterified OH groups or optionally solubilizing by enzymes. This method can be used, for example, for the separation of mixed epimers of vitamin D analogs. |
