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
