Abstract

A process for the preparation of D-homosteroids of the general formula ** (Formula) ** in which R1 and R2 each represent a hydrogen atom or R1 and R2 together represent a 1alpha, 2alpha-methylene group or a carbon-carbon bond; R6 represents a fluorine or chlorine atom; R17a represents a hydroxyl, acyloxy, alkoxy or lower alkyl group; R10 represents the methyl group or when R1 and R2 each represent a hydrogen atom, R10 can also represent a hydrogen atom; R21 represents a hydrogen, fluorine or chlorine atom and the dashed line at position 6,7 denotes an optional carbon-carbon bond.
