We present a study of the Diels-Alder reaction between various electron-deficient 2H-pyran-2-ones and ethyl vinyl ether. This microwave-accelerated sequence of a cycloaddition followed by a retro-Diels-Alder reaction (the elimination of CO2) and a second elimination step of EtOH yields substituted aniline derivatives. The reaction sequence is greatly accelerated by the application of DABCO as a suitable base.
