Synthesis of several α-methoxy phosphonates with the phosphorus as a part of 1,3,2-dioxaphosphorinane ring by the simple reaction of (OCH 2 CMe 2 CH 2 O)PCl with acetals is described. Analogous methoxy phosphonates using (′)(C 2 0 H 1 2 O 2 )PCl were also synthesized using the same route. Utility of these phosphonates in the synthesis of vinyl ethers via the Horner-Wadsworth-Emmons [HWE] reaction is
描述了通过 (OCH 2 CMe 2 CH 2 O)PCl 与缩醛的简单反应合成几种 α-甲氧基膦酸酯,其中磷作为 1,3,2-二氧杂膦环的一部分。使用 (')(C 2 0 H 1 2 O 2 )PCl 的类似甲氧基膦酸酯也使用相同的路线合成。证明了这些膦酸盐在通过 Horner-Wadsworth-Emmons [HWE] 反应合成乙烯基醚中的效用。
