goniomitine, new synthetic bio‐inspired fragmentation strategies for the synthesis of functionalized 2‐quinolinones and indolones have been developed. Remarkable synthetic efficiency was achieved by telescoping several transformations into one‐pot reactions, allowing for the direct coupling of 2‐alkynyl‐anilines and diazo ketones. The synthetic utility was demonstrated by the 5‐step asymmetric total synthesis
