Abstract

A facile strategy for the preparation of two isomeric drospirenones 13 and 16 possessing a 14β-hydrogen was developed, using 3β-hydroxyandrost-5-en-17-one as the starting material. The total synthetic route involves eight steps, giving 2% overall yield. The structures of the main compounds 11, 13, 14 and 16 were determined by single crystal XRD analysis.
