Cyanoacetamide reacted with 3β-hydroxy-16-hydroxymethylene-5-androsten-17-one to form 1-cyano-2-hydroxy-2(16′-3′β-hydroxy-17′-oxo-5′-androstenyl) propionamide or 3-cyano-4,5-dehydro-6-hydroxy-5,6(16′,17′-3′β-hydroxy-5′-androstenyl)-2-piperidone depending on whether a catalytic or a molecular amount of piperidine was used as the basic condensing agent. Carboxamidoacetamidine, and acetamidine hydrochlorides
氰基乙酰胺与 3β-羟基-16-羟基亚甲基-5-雄烯基-17-酮反应生成 1-氰基-2-羟基-2(16'-3'β-羟基-17'-氧代-5'-雄烯基)丙酰胺或 3-cyano-4,5-dehydro-6-hydroxy-5,6(16',17'-3'β-hydroxy-5'-androstenyl)-2-piperidone 取决于催化或分子量哌啶用作碱性缩合剂。Carboxamidoacetamidine 和乙脒盐酸盐与 3β-hydroxy-16-hydroxymethylene-5-androsten-17-one 和 3β-chloro-16-chloromethylene-5-androsten-17-one 的钠盐缩合,生成 2-amino- 3-carboxamido-5,6(16', 17'-3'β-hydroxy-5'-androstenyl) pyridine and 2-methyl-5
