Abstract
A series of novel pyridine-bridged 2,6-bis-carboxamide N-β-glycosides and Schiff's bases has been prepared starting from 2,6-bis-carboxamide pyridine hydrazide, which on treatment with appropriate monosaccharides, aromatic or heterocyclic aldehydes, and indoline-2,3-dione derivatives afforded the corresponding sugar hydrazones and pyridine-bridged 2,6-bis-carboxamide Schiff's bases.
