Abstract

The invention comprises steroids of the formula <FORM:0911750/IV (b)/1> (wherein R1 is an acyl group of at most 6 carbon atoms and R is alkyl, haloalkyl, aralkyl, aralkenyl, cycloalkyl, cycloalkyl-alkyl, aryl, carbalkoxyalkyl or furfuryl) and their preparation by reacting the corresponding 3-oxo-D 4-steroid with the appropriate alcohol ROH or an acetone acetal or orthoformic acid ester thereof in the presence of a catalytic quantity of hydrogen ions. Examples are given. In the Provisional Specification R is additionally defined as an alkenyl, carboxyalkyl or heterocyclic group. Specification 858,033 is referred to.
