16Α-甲基孕甾-1,4,9(11)-三烯-17Α,21-二醇-3,20-二酮-21-醋酸酯性质、用途与生产工艺
化学性质
结晶。熔点208℃。
用途
地塞米松醋酸酯的中间体。
生产方法
可用3β-羟基孕甾-5,16-二烯-20-酮-3-醋酸酯（即妊娠双烯醇酮醋酸酯）经（16-位双键亚硝基甲基脲）加成并消除，生成3β-羟基-16β-甲基孕甾-5,16-二烯-20-酮，然后[16（17）-位]环氧化、乙酰化并环氧基开环（形成17α-羟基及15-位双键）、进而（15-位双键）催化氢化、水解（脱3-位乙酰基）、（3-位羟基）氧化（双键转至4-位）、（21-位）碘化、（21-位碘以乙酰氧基）置换、生物氧化（引入11-位羟基）（11-位羟基）磺酰化并消除[形成9（11）-双键]制得该品。
