4,6-Dimethyl-1,2,3-triazine undergoes Diels-Alder cycloaddition with enamines, derived from cyclic ketones, under microwave irradiation within 20 min. This methodology represents a dramatic improvement on the classical method and allows fused pyridine systems to be obtained, in some cases, in good yields.

triazine - microwaves - fused pyridines - Diels-Alder reaction - cyclic ketones
