A series of new phenyl esters based on a 5,16-pregnadiene-20-one skeleton, namely 3β-benzoyloxy-5,16-pregnadiene-20-ones, which may be good inhibitors of 17α-hydroxylase and 5α-reductase enzyme or useful intermediates for producing steroidal drugs, were synthesized starting from diosgenin. The structures of the steroids were characterized by 1H nuclear magnetic resonance (NMR), 13C NMR, infrared (IR), and mass spectra.
基于5,16-孕甾二烯-20-酮骨架的一系列新型苯酯类化合物,即3β-苯甲酰氧基-5,16-孕甾二烯-20-酮,可能是17α-羟化酶和5α-还原酶的优秀抑制剂,也可能是合成甾体药物的有用中间体。这些化合物从薯蓣皂苷元开始合成,并通过1H核磁共振(NMR)、13C NMR、红外(IR)和质谱对其结构进行了表征。
