Synthesis of Methyl 6,6-Dimethylfulvene-2-carboxylate and Dimethyl 6,6-Dimethylfulvene-2,3-dicarboxylate as well as their Reaction to 2,3,5,6-Substituted NorbornadienesFulvenes 5 and 6 were synthesized by Diels-Alder reaction of 6,6-dimethylfulvene with methyl prop-2-ynoate and dimethyl but-2-ynedioate, catalytic reduction of the unsubstituted norbornadiene double bond, and a subsequent retro Diels-Alder reaction under flash vacuum pyrolysis conditions, 5 and 6 are used as the diene component in synthesizing 2,5-, 2,3,5-, and 2,3,5,6-substituted norbornadienes 7-9 by Diels-Alder reaction with electron-deficient alkynes.
