    摘要:
    1α-羟基维生素 D3(XIVa)由胆固醇(Ia)合成,总收率约为 1.5%。1α,2α-环氧胆甾烷-4-烯-3-酮(IVa)很容易从 Ia 中获得,通过在 DMSO 中与 t-BuOK 的改进脱钩反应转化为 1α,2α-环氧胆甾烷-5-烯-3-酮(Va)。用 Ca (BH4)2 还原 Va,然后用 LiAlH4 还原,从 Ia 得到 1α-hydroxycholesterol (VIIIa),收率为 15.6%。对 VIIIa 的二乙酸酯进行烯丙基溴化和随后的脱氢溴化,可得到 1α,3β-二乙酰氧基胆甾烷-5,7-二烯(XIa),对其进行皂化可得到相应的二醇(XIIa)。乙醇中的 1α-羟基维生素 D3(XIIa)通过新发现的滤液,在 275 至 310 纳米范围内接受紫外线照射。生成的 1α-羟基维生素 D3(XIIIa)经热异构化为 1α-羟基维生素 D3。从 XIIa 生成 XIVa 的产率约为 25%。将这些步骤应用于 25-羟基胆固醇(Ib),从 Ib 中得到 1α,25-二羟基维生素 D3(XIVb),总产率约为 0.4%。
