Protected primary phosphine oxides may be obtained by reaction of ethyl (diethoxyalkyl)phosphinates with organometallic reagents. These products, stable to chromatography or distillation, may be further elaborated into new, functional unsymmetrical secondary and tertiary phosphine oxides. A close analogue of muscarinic antagonists has been prepared using this methodology.
二乙氧基烷基)膦酸乙酯与有机金属试剂反应可获得受保护的一级膦氧化物。这些对色谱法或蒸馏法稳定的产物可以进一步加工成新的、功能性不对称的二级和三级膦氧化物。利用这种方法制备出了毒蕈碱拮抗剂的近似物。
