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

A palladium-catalyzed oxidative cross-coupling of vinyl boronic acids and cyclic α-diazocarbonyl compounds has been reported. The reaction constitutes an efficient method for the synthesis of 1,3-diene compounds bearing a ring structure. Mechanistically, the reaction involves migratory insertion of palladium carbene as the key step.
