CYCLIZATION OF NITRILES. XXVII. SYNTHESIS OF ANNELLATED PYRIDINES AND THIENOPYRIDINES BASED ON PREGNA-5,16-DIEN-3β-OL-20-ONE AND METHYLENE-ACTIVE NITRILES. MOLECULAR AND CRYSTAL STRUCTURE OF 3'-AMINO-6'-METHYL-2'-CYANO-3Β-HYDROXYANDROST-5-ENOTHIENOPYRIDINE

The addition of methylene-active nitriles to pregna-5,16-dien-3β-ol-20-one acetate by Michael rection takes place stereoselectively and leads t the formation of 16α-substituted pregna-5-en-3β-ol-20-ones. (5-Pregnen-3β-ol-20-on-16α-yl)cyanothioacetamide was converted into 16α-(4-aryl-2-thiazolyl)pregna-5-en-3β-ol-20-ones and 2'-methyl-5'-cyano-3β-hydroxyandrost-5-enopyridine-6'(1'H)-thione.Alkylation of the latter gave 2'-substituted 3'-amino-6'-methyl-3β-hydroxyandrost-5-enothienopyridines.The crystals of3'-amino-6'-methyl-2'-cyano-3β-hydroxyandrost-5-enothienopyridine are constructed of two symmetrically independent molecules.
