| titleOfInvention | PROCEDURE FOR THE PREPARATION OF SILILIC ETHERES OF STEROIDS. |
| abstract | Procedure for the preparation of steroid silyl ethers of the general formula **(See formula)** in which R stands for hydrogen, methyl or chlorine; R1 signifies hydrogen or methyl; R2 signifies a radical R4 or R5; R4 signifies a group -Osi (Alk) 3 or OAc; Alk means a lower alkyl group; Ac means a lower alkanoyl group; R5 signifies a group -COCH3, -COCH2OAc, -COCH2OSi (Alk) 3, -CH (OAc) CH3 or -CH (OS1 (Alk) 3) CH3; R3, in the case that R2 represents a radical R4, means a radical R6 and, in the case that R2 represents a radical R5, it means a radical R4 or R7; R6 signifies a R7 or ethynyl radical; R7 signifies hydrogen, methyl, ethyl or vinyl; Y means hydrogen, or in the case that R2 represents a radical R5, also fluorine; Z signifies methylene or a radical Z1; and Z1 signifies a carbonyl group or a -CHOSi (Alk) 3 group, and its derivatives delta5 (6) -dehydro and delta1,5 (6) -bisdehydro, **(See formula)** in which R21 signifies a radical R2, a hydroxy group or a group -COCH2OH or -CHOHCH3; R31, in the case that R21 represents a radical R4 or a hydroxylic group, means a radical R6 and, in the event that R21 represents a radical R5 or a group -COCH2OH or -CHOHCH3, it means a radical R4 or R7 or a hydroxyl group; and Z signifies a radical Z or a -CHOH group, with a trialkylsilylation agent and a compound of formula I is isolated from the reaction product.
