The preparation of the following steroid phosphorodichloridates is described: cholestanyl, epicholestanyl, epicholesteryl, and the derivatives of methyl 3α-hydroxy-5β-chlolanate, and ergosta-8(14)en-3β-ol. The formation of the phosphorodichloridates was followed by t.l.c. Attempted phosphorylation of 3,5-cyclocholestan-6β-ol, and 6β-hydroxycholest-4-en-3-ol gave cholesteryl phosphorodichloridate and
描述了以下甾族二氯磷酸酯的制备:胆甾烷基,表胆固醇基,表胆固醇基以及3α-羟基-5β-氯戊酸甲酯的衍生物和ergosta-8(14)en-3β-ol。形成二氯二氯磷酸酯后,进行薄层色谱(tlc)。尝试将3,5-环胆甾烷-6β-ol和6β-羟基胆甾醇4-en-3-ol磷酸化,分别得到胆甾醇基二氯磷酸酯和胆甾烷3,6-二酮。已经在各种条件下检查了胆固醇二磷酸二氯酯的水解。类固醇二氯化磷已用甲醇处理。胆磷酸二氯胆固醇酯与多种醇的反应,得到相应的胆甾醇醚。用干燥的吡啶溶剂化二氯化磷,得到相应的N-类固醇吡啶鎓氯化物。
