Dioxirane oxidation of substituted vinylphosphonates: a novel efficient route to 1,2-epoxyalkylphosphonates
摘要:
A new stereoselective route to substituted 1,2-epoxyalkylphosphonates through oxidation of corresponding alk-1-enylphosphonates by 'in situ' generated ethylmethyldioxirane is described. (C) 1998 Elsevier Science S.A. All rights reserved.
A stereoselective synthesis of disubstituted diethyl alk-1-enylphosphonates has been developed via syn addition of RMgX/CuCl to alk-1-inylphosphonates.
Facile and stereoselective synthesis of vinylphosphonates
Stereoselective syntheses of mono-, di- and trisubstituted diethyl alk-l-enylphosphonates, starting from readily available alk-1ynylphosphonates, have been developed, using catalytic hydrogenation or cuprate addition on the triple bond.
