Process for the preparation of 6alpha-fluoro steroids by isomerisation of 6beta-fluorosteroids

摘要

The process for the preparation of 6alpha-fluoro steroids, comprising the reaction of the corresponding 6beta-fluoro steroids, or of 6alpha/6beta isomeric mixtures with an organic base having a diazo iminic group, in a suitably selected organic solvent, is described.
