The lower reactivity of dimethyl maleate is explained by steric effects between the dienophile substituents and the diene. The transition states become more crowded when the carboalkoxy groups are cis.

    • (a) Reaction of dimethyl maleate with α,α′-dimethyl-o-quinodimethane generated by fluoride-induced elimination yields cis-2,3-dicarbomethoxy-1,4-dimethyl-1,2,3,4-tetrahydronaphthalene. The product is formed because the o-quinodimethane cannot undergo 1,5-sigmatropic rearrangement. Cycloaddition of dimethyl maleate to yield the cis adduct also occurs with the unsubstituted o-quinodimethane, which cannot undergo 1,5-sigmatropic rearrangement. Ito, Y.; Nakatsuda, M.; Saegusa, T.
