A tandem Diels-Alder cyclization/aromatization of 5-vinyl-2,3-dihydro-4-pyridones and various dienophiles is reported. The intermediate Diels-Alder cycloadduct undergoes an elimination/aromatization to provide b-amino-ketones, b-amino-alcohols, and unnatural amino acids containing useful functionali
