SYNTHESIS AND CHARACTERISATION OF SOME NEW N-GLYCOSIDES CONTAINING SUBSTITUTED PYRIDOPYRIMIDINONE, PYRIMIDOPYRIDAZINONE, THIAZOLOPYRIMIDINONE AND QUINOLIZIN-4-ONE MOIETY

摘要

A series of new N-glycosides (D-glucosides, D-mannosides, L- and D-arabinosides, D-xylosides and one D-galactoside) containing heterocyclic moiety have been prepared by reaction of the corresponding heterocyclic amines with pyranoses in boiling methanol. The structures of the prepared compounds have been studied by means of proton and carbon NMR spectroscopy. In the most cases the products existed in DMSO solution as the single anomers.
