N-substituted phosphoramidic chloride was obtained from the reaction of amines with POCl_3,then hydrazinolyzation gave N-substituted phosphoramidohydrazide(2a-2g).Refluxing of 2 with glucosyl isothiocyanate(1)in CHCl_3 gave corresponding N,N′-substituted-N″-(2,3,4,6-tetra-O-acetylglucosylthioureylen...
