title: Hydride-donor abilities of 1,4-dihydropyridines: a comparison with pi nucleophiles and borohydride anions.
abstract: How are dihydropyridines like indoles? Both groups of compounds have similar nucleophilicity parameters N and are therefore suitable substrates for iminium-catalyzed reactions of alpha,beta-unsaturated aldehydes. The N parameters of 1,4-dihydropyridines were derived from the rates of hydride transfer reactions to benzhydrylium ions (see scheme).
