bulky diol derivatives prefer ansa- or bridged products by reacting with cyclotriphosphazene. But, surprisingly, dicoumarol which is also bulky diol derivative gave only spiro products in this study. The molecularstructures of compounds (3–5) were also determined by X-ray crystallography. The crystalstructures of these compounds were solved by direct methods and refined by full-matrix least squares
在目前的工作中,香豆素取代的环三磷腈首次被设计,合成和表征。3,3'-亚甲基二(4-羟基香豆素),(双香豆素,钠衍生物的反应1)中,用环三磷腈,(N 3 P 3氯6,2),在THF溶液中,得到单-螺(3),双螺环(4)和三螺环(5)双香豆素取代的化合物。所有dicoumaroxy取代环三磷腈化合物(3 - 5)得到充分表征通过元素分析,IR,ESI质谱,1 H和311 H NMR光谱。通常,大体积的二醇衍生物通过与环三磷腈反应而更优选邻氨基苯甲酸酯或桥联产物。但是,令人惊讶的是,在本研究中,也是粗大的二醇衍生物的双香豆酚只产生了螺环产物。化合物(的分子结构3 - 5)也通过X射线晶体学确定。这些化合物的晶体结构通过直接方法解析,并通过全矩阵最小二乘法精炼。
