Abstract

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 51 provided the novel spirocycle 61.
