The ten possible substitution patterns for N-ethoxycarbonyl-2-methyl-1,2-dihydropyridines 5 in which one or two olefinic sites are alkyl substituted were synthesized and reacted with N-phenylmaleimide 2 to provide cycloadducts 6.N-ethoxycarbonyl-5,6-cyclohexyl-2-methyl-1,2-dihydropyridine 5l provided the novel spirocycle 6l.
