Abstract

A procedure for the preparation of the 21-hydroxy steroids of the pregnane series esterified in position 21 which correspond to the general formula: ** (See formula) ** wherein St represents a steroid radical, where R: H, OH or OR 'is represented by R', a lower acyl radical, where n and hereinafter an integer less than 3, characterized in that it is esterified in position 21 , a 20-oxo 21-hydroxy steroid of the pregnane series with an organic acid of formula ** (See formula) ** or a functional derivative of this.
