Synthesis of 1-(Substituted Phenylcarbonyl/sulfonylamino)-1,2,3,6-tetrahydropyridine-5-carboxylic acid diethylamides as Potential Anti-inflammatory Agents

Fifteen novel 1-(substituted phenylcarbonyl/sulfonylamino)-1,2,3,6-tetrahydro- pyridine-5-carboxylic acid diethylamide (7, 15) were synthesized in fair to good yields via sodium borohydride reduction of the corresponding 1-(substituted phenylcarbonyl/ sulfonylimino)-3-diethylcarbamoyl pyridinium ylides (6, 14) in absolute ethanol.
