MICROBIOLOGICAL METHOD FOR THE PRODUCTION OF 7 ALPHA-SUBSTITUTED 11 ALPHA-HYDROXYSTEROIDS

摘要

Disclosed is a new synthetic pathway for the production of precursors for the production of compounds having general formula (8,10,12). During said synthesis, compounds of general formal (4,B) are produced in a microbiological reaction. The meanings of radicals R<7>, R<10>, R<11>, R<13>, R<17> and R<17'> and group U-V-W-X-Y-Z are defined in the patent claims.
