Synthesis of O-aryl N4-glycosyl(thiosemicarbazido) phosphonothioates

A reaction of aryl(aryloxy)thiophosphonic acids hydrazides with glycosyl isothiocyanates was studied. Amides of N-(glycosylthioureylene)aryl(aryloxy) thiophosphonic acids were synthesized. The structure and composition of the new compounds were confirmed by the data of IR, 1H and 31P NMR and mass spectra, and by results of elemental analyses.

SYNTHESIS AND NMR SPECTROSCOPIC INVESTIGATION OF PHENYLPHOSPHORYL DERIVATIVES

The syntheses of 16 phenyl- (1 and 3) and phenylthiophosphoryl (2) derivatives are described.The 13C and 17O NMR data sensitively reflect electron density changes in the phosphoryl substituents caused by p?-d? back-donation from X/Y to P.Taft constants ?1 and ?R0 were derived for 16 phosphoryl substituents.
