Condensation of 17β-acetoxy-2α-bromo-5α-androstan-3-one with unsubstituted and substituted amino-pyridines, gives the corresponding 17β-acetoxy-5α-androstanimidazo[1,2-a]pyridines. Treatment of 16α-bromo-3-aza-A-homo-4α-androsten-4,17-dione with 2-aminopyridine or methyl-2-aminopyridine produces the corresponding 3-aza-A-homo-4α-androsten[16,17:2′,3′]imidazo[1,2-a]pyridines. Similarly, from 2α-bro
17β-乙酰氧基-2α-溴-5α-雄烷-3-酮与未取代和取代的氨基吡啶缩合,得到相应的17β-乙酰氧基-5α-雄烷二咪唑并[1,2- a ]吡啶。用2-氨基吡啶或甲基-2-氨基吡啶处理16α-溴-3-氮杂-A-homo-4α-雄酮-4,17-二酮产生相应的3-氮杂-A-homo-4α-雄酮[16, 17:2',3']咪唑并[1,2- a ]吡啶。类似地,从2α-溴-17β-乙酰氨基-5α-雄烷-3-酮和甲基氨基吡啶中,已经得到17β-乙酰氨基-5α-雄烷[2,3:2',3']咪唑并[1,2- a ]甲基吡啶获得。
