Abstract
Reaction of 2,3,4,5-tetra-O-acetylgalactaric acid bis 1,6-[methylthio or benzylthio (thiocarbonyl)]hydrazides 1, 2 with different bifunction al amines [piperazine (PPZ), tetraethylethylenediamine (TEED), tetrame thylethylenediamine (TMED), and tetramethylpropanediamine (TMPD)] in m ethanol, gave the corresponding monomeric, and polymeric saccharide am ine salts according to saccharide bishydrazide : diamine ratioes. The elucidation of structures for the prepared compounds is discussed and mechanistic pathways for their formation are proposed.
