Abstract

Prepn. of gona-4,9-dien-3,17-diones of formula (I) (where R is 1-4C alkyl) by treating a gona-1,3,5(10)-trien-17-one of formula (II) (where X is H, 1-6C alkyl or is not >16C acyl) with HF/SbF5. Cpds (I) are inters for active steroids e.g. 4,9,11-trienes. They are prepd. simply in good yield by a single-stage process. The preferred molar ratio of SbF5/HF is 5 to 20% to give optimum yields and speed of reaction.
