英文摘要: By means of H-1,C-13, B-11 NMR, polar transfer DEPT135, DEPT90 and 2D NMR experiments, IR, etc, the structure of the diaminodihydroxyl ligand and its derivatives used in the asymmetric reduction of prochiral ketones were detected. The catalysts derived from the ligand and borane formed in situ were also studied and the structure transformations in solution were monitored. The structure of the catalyst was proved to be a new type of dual-centered catalyst-bisoxazaborolidine.
