Synthesis and characterization 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) contg. heterocyclic moiety have been prepd. by reaction of the corresponding heterocyclic amines with pyranoses in boiling methanol. The structures of the prepd. compds. have been studied by means of proton and carbon NMR spectroscopy. In the most cases the products existed in DMSO soln. as the single anomers.
