corresponding diketone. These bis(β-hydroxyalkyl)phosphane derivatives are suitable chiral starting materials for the synthesis of 1-phospha-10-aza-18-crown-6 derivatives, the first examples of optically pure, crown-ether-like, phosphorus-containing macrocycles. One of them has been characterised by X-ray diffraction study. Complexation of Na+ by the crown ether moiety of the macrocyclic ring has been observed
(S,S)-双(2-羟丙基)(苯基)氧化膦,通过(S)-氧化丙烯与二锂(苯基)膦的开环或双(2-氧丙基)催化氢化制备(苯基)氧化膦,由钌/MeO-BIPHEP促进。催化氢化还允许从相应的二酮对映选择性合成(R,R)-双(2-苯基-2-羟乙基)(苯基)氧化膦。这些双(β-羟烷基)膦衍生物是合成 1-phospha-10-aza-18-crown-6 衍生物的合适手性原料,这是光学纯、冠醚类、含磷大环的第一个例子. 其中之一已通过 X 射线衍射研究进行了表征。已通过 1 H NMR 分析观察到 Na+ 与大环的冠醚部分发生络合。(© Wiley-VCH Verlag GmbH & Co.
