Process for preparing 1-hydroxylated vitamin D compounds from 5,6-trans-vitamin D compounds |
| abstract |
A method for preparing 1α-hydroxylated vitamin D compounds from 5,6-trans-vitamin D compounds which comprises allylically oxidizing a 5,6-trans-vitamin D compound, subjecting the oxidation product to actinic radiation in the presence of a photosensitizing agent and recovering the 1α-hydroxylated compound. n 1α-hydroxylation is recognized as being essential to impart biological activity to vitamin D compounds and their derivatives. The present invention provides an efficient method for maximizing the yield of 1α-hydroxylated vitamin D compounds. |
