Latest Patents
Among his latest patents, one notable invention is the hydroxylation process. This process allows for the preparation of biologically active 1.alpha.-hydroxyvitamin D compounds from vitamin D compounds through hydroxylation at carbon 1, followed by photochemical isomerization. Additionally, he has developed a method for preparing 1-hydroxylated vitamin D compounds from 5,6-trans-vitamin D compounds. This method involves allylically oxidizing a 5,6-trans-vitamin D compound, exposing the oxidation product to actinic radiation in the presence of a photosensitizing agent, and recovering the 1.alpha.-hydroxylated compound. The efficiency of this method maximizes the yield of 1.alpha.-hydroxylated vitamin D compounds, which are essential for imparting biological activity to vitamin D and its derivatives.
