摘要：
A novel oxidative amination of sp(3) C-H bonds was developed for the efficient synthesis of imidazo[1,5-a]quinolines from readily available -amino acids and (2-azaaryl)methanes. This domino protocol, which was established in a TBAI-TBHP oxidation system, includes transition-metal-free decarboxylation and intramolecular cyclization. This method represented a new avenue for the synthesis of N-heterocycles using 2-methylquinolines as the synthon of quinoline-2-carbaldehydes.
