Treatment of quinolines and isoquinolines with benzoyl peroxide in tertiary amides, such as N,N-dimethylacetamide, N,N-dimethylpropionamide, and N-acetylpyrrolidine, etc., under irradiation with a Hg lamp in the temperature range of 35 °C to 40 °C gave C–C-bonded quinolines and isoquinolines bearing amide groups with high regioselectivity in good to moderate yields, respectively, under transition-metal-free
在35°C至40°C的Hg灯照射下,在N,N-二甲基乙酰胺,N,N-二甲基丙酰胺和N-乙酰基吡咯烷等叔酰胺中用过氧化苯甲酰处理喹啉和异喹啉。在无过渡金属条件下,°C可使带有酰胺基团的C–C键合喹啉和异喹啉分别具有良好的区域选择性,并具有良好的区域选择性。
