Abstract

Stereoselective reaction of tetramethyl ethynyldiphosphonate with diethyl 2-amidomalonates yielded Z-vinyldiphosphonates, namely Z-2-[1,2-bis(dimethoxyphosphoryl)-2-alkyl(aryl)amidovinyl]malonic acid diethyl esters. A possibility of cyclization of the amidomalonate fragment of the obtained alkenes with the formation of an oxazole-substituted Z-vinyldiphosphonate was shown.
