Enzymatic process for 17 Alpha cortexolona monoesters of 9.11 Dehydro - and / or its derivatives

摘要

This application concerns a New Enzymatic process to obtain 17 alpha - cortexolona monoesters and / or their 9.11 - Dehydro derived from the corresponding diesters 21 - 17 Alpha, which comprises an Enzymatic alcoholysis reaction. This also refers to New Crystalline forms of the 17 alpha - propionate and butyrate cortexolona 17 Alpha Dehydro - cortexolona 9.11.
