Abstract

A procedure for the preparation of new 3-desoxo-19-nor-steroids, characterized by preparing a compound of the formula ** (See formula) ** where R1 = an alcohol group with 1-3 C atoms, R2 = hydrogen, an acyl group or an ether group, R3 = hydrogen or an alcohol, alkenyl or lower alkynyl group with 1-6 carbon atoms, or OR2 + R3 together form a keto group, R4 = an alcohol group with 1-4 C atoms, and in which there is a double bond that starts from carbon atom 5, starting from the corresponding oxygenated compound in position 3, which at position 17 you can already have the substituents indicated in the above formula, by cleavage by reduction of the substituent at position 3, and then introducing, if desired, the substituents indicated at position 17 by any method known per se.
