Abstract

Inspired by the biogenetic origin of 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 of (-)-goniomitine from 2-ethyl-cyclopentanone.
