SELECTIVE ENZYMATIC ESTERIFICATION AND SOLVOLYSIS OF EPIMERIC VITAMIN D ANALOG AND SEPARATION OF THE EPIMERS

摘要

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 method can be used, for example, for separating mixed epimers of the vitamin D analog.
