Intramolecular Diels-Alder reactions of 1,2,4-triazines. Synthesis of 2,3-cyclopentenopyridines and 5,6,7,8-tetrahydroquinolines
摘要:
2,3-Cyclopentenopyridines and 5,6,7,8-tetrahydroquinolines are prepared by intramolecular Diels-Alder reactions of appropriately substituted 1,2,4-triazines. Two general routes to the requisite triazine precursors are described.
