The copper-catalyzed aerobic oxidative synthesis of imidazo[1,5-a]pyridines via cascade denitrogenative transannulation reaction of pyridotriazoles with benzylamines with good functional group tolerance is developed. The present methodology is also applicable to amino acids to obtain imidazo[1,5-a]pyridines via decarboxylative oxidative cyclization.
通过吡啶三唑与具有良好官能团耐受性的苄胺的级联脱氮环氧化反应,开发了铜催化的咪唑并[1,5- a ]吡啶的好氧氧化合成反应。本方法学也适用于氨基酸,通过脱羧氧化环化获得咪唑并[1,5- a ]吡啶。
