Cy. Yuan et Sj. Chen, STUDIES ON ORGANOPHOSPHORUS COMPOUNDS 100 - STEREOSELECTIVE SYNTHESISOF 2-SUBSTITUTED ISOXAZOLINYL METHYLPHOSPHONATES, Phosphorus, sulfur and silicon and the related elements, 123, 1997, pp. 111-118
Reaction of dialkyl 1-hydroxy aminophosphonates with aldehydes leads t
o a nitrone bearing phosphonate moiety. The phosphoryl nitrone thus ob
tained provides (Z) 2-substituted isoxazolinyl methylphosphonates upon
reaction with maleic anhydride as a 1,3-dipolar cycloaddition product
.
