N-Allyl-substituted aminomethylene-1,1-bisphosphonates in 1,3-dipolar cycloaddition reaction with aromatic nitrile N-oxides

A reaction of N -allyl-substituted aminomethylene-1,1-bisphosphonates with aromatic nitrile N -oxides was used to obtain new aminomethylenebisphosphonates with one or two 3-arylisoxazoline rings at the nitrogen atom. NMR spectroscopy studies showed that the bisphosphonates with two isoxazoline fragm...

Description
Summary:	A reaction of N -allyl-substituted aminomethylene-1,1-bisphosphonates with aromatic nitrile N -oxides was used to obtain new aminomethylenebisphosphonates with one or two 3-arylisoxazoline rings at the nitrogen atom. NMR spectroscopy studies showed that the bisphosphonates with two isoxazoline fragments in the molecule exist in solution as a mixture of two diastereomers.
