| dc.description.abstract | Described is the efficiency of cinchona-derived quaternary ammonium salts as Lewis acid organo-catalysts in aza Diels-Alder reaction of Danishefsky's diene 1 with imines 2 and 16, providing 1,2-dialkyl-2,3-dihydro-4-pyridinones 3 and cyclic dihydropyridones 17, respectively. Among the nine of cinchonidine-derived quaternary ammonium catalysts prepared. N-2',3',4'-trifluorobenzyl-O-benzylcin-chonidinum bromide (6) exhibited the highest chemical yield (up to 99%). Systematic study on structure-catalytic efficiency relationship revealed that 2',3',4'-trifluorobenzyl, quinuclidine, and quinoline moieties are essential. (C) 2010 Elsevier Ltd.
