precursors (ortho-bromoaryloxy)diazaphosphospholidine–borane complexes 3a–3h, and on a stereoselective P–O to P–C migration rearrangement. A X-ray diffraction study of the structures of the product 4f and his precursor 3f shows unambiguously the totally stereoselectivity of the P–O to P–C rearrangement with clean retention of the phosphorus configuration.(© Wiley-VCH Verlag GmbH & Co.

描述了以硼烷配合物 4a-4h 的形式完全非对映选择性合成新的 P-立体(邻羟基芳基)二氮杂磷脂。该过程的效率基于前体(邻溴芳氧基)二氮杂磷磷脂-硼烷复合物 3a-3h 的一锅法和完全非对映选择性合成,以及立体选择性 P-O 到 P-C 迁移重排。产物 4f 及其前体 3f 结构的 X 射线衍射研究清楚地表明 P-O 到 P-C 重排的完全立体选择性,同时保留了磷构型。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 魏因海姆, 德国, 2006)
