SYNTHESIS OF N-SUBSTITUTED CARBONYLAMINO-1,2,3,6-TETRAHYDROPYRIDINES AS POTENTIAL ANTI-INFLAMMATORY AGENTS.

Several N-substituted carbonyl/sulfonylamino-1,2,3,6-tetrahydropyridines (5a-i and 9a, b) were synthesized via sodium borohydride reduction of the corresponding N-substitutedimino-pyridinium ylides (4a-i and 8a, b) in absolute ethanol.
