Very simple one-step synthesis of vinylphosphonates and enamine phosphonates by direct addition of organolithium reagents to 1-alkynylphosphonates

Direct addition of organolithium to 1-alkynylphosphonates (1) afforded vinylphosphonates and enamine phosphonates (2) in good to excellent yields. The reaction was carried out in dry THF at low temperature and proved to be completely stereoselective (syn

Facile and stereoselective synthesis of vinylphosphonates

Stereoselective syntheses of mono-, di- and trisubstituted diethyl alk-1-enylphosphonates, starting from readily available alk-1-ynylphosphonates, have been developed, using catalytic hydrogenation or cuprate addition on the triple bond.
