Regioselective facile one-pot Friedländer synthesis of sugar-based heterocyclic biomolecules Original Research Article

Regioselective facile one-pot synthesis of 16 different sugar-based quinoline, naphthyridine, and xanthone derivatives is reported. The compounds are characterized by NMR spectroscopy and elemental analysis. The β-Anomeric form of the sugar moiety was identified from 1H NMR studies. Antimicrobial studies of these sugar–heterocyclic derivatives, 3a, 3b, 3f, 5c, 7a, 7b, and 7c show excellent activity against different microbes.
