| titleOfInvention | PROCEDURE FOR THE PREPARATION OF A STEROID- (17 ALPHA16 ALPHA-D) - OXAZOLIDINE. |
| abstract | Procedure for the preparation of a steroid- (17α,16α-d) -oxazolidine, with a coupled cyclopentanooxazoline ring system, of the formula, ** (See formula) ** wherein R" represents an element selected from hydrogen and the aryl, aralkyl and lower alkyl groups, characterized in that a steroid of the series 16β,17β-epoxy-20-keto-17β-pregnane, is refluxed, with sodium azide in a solvent, in the presence of an amount of an acid capable of releasing free hydrazoic acid from its salts, reacting 16α-hydroxy-17α-azide with an agent chosen from anhydrides and acyl chlorides of aliphatic and lower aromatic carboxylic acids, and the catalytic hydrogenation of 16α-acyloxy-17α-azide, in the presence of a metal chosen from platinum, palladium and nickel, as a catalyst.
