This invention relates to processes for the preparation of novel , substituted steroid compounds of Formula 1, wherein R1 is H or. COR2; R2 is C1-C6 alkyl or Ct-C6 alkoxy; Z1 is CH2, or wherein OR3 is in the .alpha. configuration; R3 is H or -COR2; Z2 is -CH-; or Z1 and Z2 may be taken together to form a carbon- carbon double bond; Q is or Y is --CN, -CH2-CH=CH2, C1-6. Alkyl C1-6 alkyl CHR4C (O)Ar, or CHR4 C (O)XC1-6 alkyl; CHR4(O)XAr, or CHR4 HC(O)XC1.6 alkyl; where R4 = O C1-6 alkyl or aryl X=Oor S i

L'invention concerne des procédés de préparation de nouveaux composés de stéroïde substitués de formule 1. Dans cette formule, R¿1? représente H ou COR¿2?, R¿2? représente C¿1?-C¿6? alkyle ou C¿1?-C¿6? alkoxy, Z¿1? représente CH¿2? ou (A), OR3 se trouvant dans la configuration .alpha., R¿3? représente H ou -COR¿2,? Z¿2? représente -CH-, ou Z¿1? et Z¿2? peuvent être pris ensemble pour former une liaison double carbone-carbone, Q représente (B), (C) ou (D), (E), (F), Y représente -CN, -CH¿2?-CH=CH¿2?, (G)C¿1-6? alkyle, (H)C¿1?-¿6? alkyle, CHR¿4?C(O)Ar, ou CHR¿4?C(O)XC¿1-6 ?alkyle, CHR¿4?C(O)XAr ou CHR¿4?C(O)XC¿1-6? alkyle, R¿4? représentant O C¿1?-¿6? alkyle ou aryle, X représentant O ou Si.
