A domino reaction sequence has been evaluated that begins with union of novel dihydrooxazinone precursors with 2-alkynyl-substituted benzaldehyde components through aldol condensation. Ensuing operations, including alkene isomerization, Diels-Alder, and retrograde Diels-Alder with loss of CO occurs in the same reaction vessel to provide polysubstituted tricyclic pyridine products.
已经评估了一种多米诺反应序列,该序列始于新型二氢恶嗪酮前体与2-炔基取代的苯甲醛组分通过羟醛缩合反应结合。随后的操作,包括烯烃异构化、狄尔斯-阿尔德反应以及伴随CO损失的逆向狄尔斯-阿尔德反应,均在同一反应容器中进行,以提供多取代的三环吡啶产物。
