The Intramolecular Diels-Alderreactions of furans possessing a 2-alkyl substituent with a terminal α,β-unsaturated ketone have been surveyed. The consequences of varying the degree of substitution of the furan, the bridging chain length, and position of the activating group on the dienophile upon the ease and stereochemistry of cycloaddition are reported.
