Intramolecular inverse electron demand Diels-Alder reactions of 1,2,4-triazines have been effectively utilized for the synthesis of furo[2,3-b] pyridines, 2,3-dihydropyrano[2,3-b]pyridines, and 2,3-dihydropyrrolo-[2,3-b]pyridines.
1,2,4-三嗪的分子内逆电子需求Diels-Alder反应已被有效地用于合成呋喃[2,3-b]吡啶,2,3-二氢吡喃[2,3-b]吡啶和2 ,3-二氢吡咯并-[2,3-b]吡啶。
