Abstract

A process for the preparation of the compounds of the general formula: ** (See formula) ** wherein R1 represents H2, O or (see formula), and R2 and R3 represent H or an acyl radical, characterized mainly by introducing bromine at positions 2 and 4 of a 3-keto 20,20-bis-hydroxymethylene steroid whose hydroxyls in 20 have been previously blocked by an acyl radical, the brominated compound is de-brominated and the primary hydroxyl groups of the 3-keto-20,20-bis-acyloxymethylene Δ 1,4-steroid obtained are liberated by saponification, optionally in organic or mineral diester, such as dinitrate.
