Aldehydes of the pregnane series and derivatives thereof

Abstract

The derivatives of 1-dehydro-6.alpha.,9.alpha.-difluoro-16.alpha.-methyl-corticosterone having an aldehyde group in 21-position instead of the hydroxyl group, and derivatives of such aldehydes having a 2-chlorine atom, the corresponding hydrates, as well as their functional aldehyde derivatives, such as the acetals, display an antiinflammatory and thymolytic action. They are prepared by conventional methods.

Dependencies are inferred from the claim text.
