Latest Patents
Oskar Jeger holds a patent for a process related to the manufacture of 1 patent. The invention focuses on the selective reduction of the 20-oxo group in Δ16-steroid-14β,18-diol-20-ones of the pregnane series. This process is designed to produce two epimeric 20-alcohols with 20S and 20R configurations. It is particularly aimed at the manufacture of alkaloids of the batrachotoxin type, including batrachotoxinine A, which features a 20S alcohol grouping. The method involves reducing the Δ16-steroid-14β,18-diol-20-ones in the form of their 14,18-ketals, utilizing complex light metal hydrides and operating at specific temperatures. The separation of the resulting isomers can be achieved through standard physical operations such as crystallization or chromatography.
