    摘要: 20-Cyano-17.alpha.-H steroids having as the 17-position substituent the group ##EQU1## wherein R is H, alkyl of 1-8 carbon atoms or benzyl, having a 13-methyl or 13-ethyl group and which are unsubstituted or substituted with an .alpha.-methyl group in the 16-position are converted to the corresponding 20-keto steroids by reaction in an aprotic solvent with a deprotonating agent containing an alkali metal, an alkaline earth metal, copper(I) or thallium(I), and optionally additionally with a copper(I) salt or a thallium(I) salt or a silver(I) salt, and thereafter conducting an oxidative splitting reaction with oxygen. The thus-produced 17.beta.-oxalyl steroids possess pharmacological activity, e.g., anti-inflammatory activity, or are useful as intermediates for the production of pharmacologically active steroids.
