The practical use of 2,2-dimethyl-2 H-pyrans as electron-rich dienes in sequential Diels-Alder/retro-Diels-Alder (DA/rDA) domino processes to generate aromatic platforms has been demonstrated. Different polysubstituted alkyl 2-naphthoates have been synthesized by the DA/rDA reaction of benzynes and 2,2-dimethyl-2 H-pyrans. The use of other activated alkynes allows the access of substituted alkyl benzoate derivatives.
