imide -amide rearrangement of cyclic phosphorimidates. As a result of this work new types of oligomeric organophosphorus compounds, formed by a novel 1,4-addition type ring opening polymerisation, were identified. These compounds are the stable intermediates of the imide-amide rearrangement, which upon heating yield the previously reported rearranged product. A detailed study of the mechanism of the Lewis
旨在开发适用于不对称化学的手性环状草酰氮和二氮杂磷酰胺的制备的新合成途径的研究使我们对环状亚磷酸酯的酰亚胺-酰胺重排进行了研究。作为这项工作的结果,鉴定了通过新型的1,4-加成型开环聚合反应形成的新型低聚有机磷化合物。这些化合物是酰亚胺-酰胺重排的稳定中间体,加热时可得到先前报道的重排产物。报道了对路易斯酸催化的酰亚胺-酰胺重排机理和最终产物的立体化学控制的详细研究。结果,阐明了完整的机理,并提出了在重新排列的碳原子处保留构型的证据。
