Abstract
A variety of new N-amino-2-pyridone and cycloalkane ring-fused pyridine derivatives containing benzothiazole moiety could be prepared via the reaction of 2-Functionally Substituted methylbenzothiazoles with activated methylene compounds. The structures of the reaction products were established based on elemental analysis and spectral data( IR, H-1 NMR, C-13 NMR, MS).
