Comparison of the rates of cyclization of a series of 2-furfuryl methyl fumarates leads to the conclusion that the gem-dimethyl effect is due primarily to higher population of reactive rotamers. Our recent observation of significant rate acceleration of the infmmolecular Diels-Alder reaction of N-f
