Abstract Intramolecular inverse electron demand cycloadditions of isatin-derived 1, 2, 4- triazines with acetylenic dienophiles tethered by amidations or transesterifications proceed in excellent yields to produce lactam-or lactone-fused α-carbolines. Beginning with various isatins and alkynyl dienophiles, a pilot-scale library of eighty-eight α-carbolines was prepared by using this robust methodology for biological evaluation.
