| titleOfInvention | Process for the stereoselective production of 14 (15) -unsaturated 17alpha-substituted steroids |
| abstract | Prodn. of 14(15)-unsatd. 17 alpha -substd. steroids of formula (I) comprises reducing a 14-hydroxy 17-one of formula (II) with a hydride transfer reagent to give a 14,17-diol of formula (III), etherifying or esterifying the 17-OH gp. to give a cpd. of formula (IV), treating (IV) with a dehydrating agent to give (I:R=R'); and opt. removing the R' gp. to give (I;R=H). X = the rest of the steroid mol.; R = H or R'; R' = 1-10C alkanoyl, aralkyl or trialkylsilyl. |
