stereoselectively with chiral l-phenylethylamines or amino acid esters to give diastereomerically enriched aminophosphines 3, which were isolated as diastereomerically pure crystalline borane complexes. Oxidation, thionation, the reaction with methyl iodide provide optically active derivatives of aminophosphines. (R,S)- and (S,S)-stereomers of phosphinic acid amides were separated by crystallization and a flash-chromatography
外消旋氯膦与手性 l-苯乙胺或氨基酸酯发生立体选择性反应,得到富含非对映异构体的氨基膦 3,将其分离为非对映异构纯结晶硼烷配合物。氧化、硫化、与甲基碘的反应提供氨基膦的旋光衍生物。次膦酸酰胺的 (R,S)-和 (S,S)-立体异构体通过结晶和快速色谱法分离。研究了磷酸酰胺的立体化学性质。三价磷原子的不对称诱导机制被合理化。
