Abstract
A method of obtaining new steroids which consists in reacting a lactone of the steroid 6,7-methylene-20-spirox-4-en-3,21-dione of formula ** (see formula) ** Where r is hydrogen or methyl; x is hydrogen or fluorine; and it is two hydrogen atoms or a hydrogen atom and a group (3-hydroxy or a keto group, and the dotted line between carbons 1 and 2 indicates that a double bond can be present in this position, with a hydrolyzing agent alkaline with which the lactone ring of said steroid lactone is hydrolysed and a 3'- (3-oxo-17 β -hydroxy-6,7-methyl-androst-4-en-17 α -il) compound is formed propionate of formula ** (see formula) ** Where e, x, y and the dotted line between carbons 1 and 2 have the meaning given above and m is the cation component of the alkaline hydrolyzing agent and acidify this alkaline hydrolysis product to form the corresponding free propionic acid compounds.
