“…Shen and Jiang developed a convenient, one-pot synthesis of ethoxycarbonyl allyl substituted oxime ethers 313 by adding ketoxime anions 311 to ethyl 2-diethoxyphosphorylacrylate (76) (Scheme 61). 70 Olefination of aromatic aldehydes using anions 312 gave oxime ethers 313.…”

Activated vinylphosphonates constitute a very important group of organic reagents which have found broad application in organic synthesis. The most important feature of activated vinylphosphonates is certainly their ability to undergo Michael additions in which a wide variety of carbo-and heteronucleophiles can be used. This review presents the potential of activated vinylphosphonates as Michael acceptors and shows possible applications of the thusformed adducts, in particular as Horner-Wadsworth-Emmons olefinating reagents, in the synthesis of important carbo-and heterocycles as well as acyclic compounds. Selected preparations of activated vinylphosphonates are also described.

“…Vinylphosphonates are important synthetic intermediates and have been investigated as biologically active compounds . Vinylphosphonates have been used as intermediates in stereoselective synthesis of trisubstituted olefins , and in heterocycle synthesis . They have been also extensively used in polymer sciences as additives or flame-retardants .…”
