The reactivity of variably substituted 2‐methyl‐4H‐3,1‐benzoxazin‐4‐ones and 2‐methyl‐4H‐pyrido[2,3‐d][1,3]oxazin‐4‐one towards carbon and oxygen nucleophiles under microwave irradiation conditions was investigated. Optimization of the reaction conditions of oxazinones with carbon nucleophiles led to the synthesis of a series of 4‐hydroxy‐quinolin‐2‐ones and 4‐hydroxy‐1,8‐naphthyridin‐2‐ones in high
可变取代的2-甲基-4 H -3,1-苯并恶嗪-4-酮和2-甲基-4 H吡啶并[2,3- d ] [1,3]恶嗪-4-酮对碳和氯的反应性研究了微波辐照条件下的氧亲核试剂。恶嗪酮与碳亲核试剂的反应条件的优化导致高产率合成了一系列4-羟基喹啉-2-酮和4-羟基-1,8-萘啶-2-酮,但反应多种多样多种醇顺利进行,形成了相应的N-乙酰基邻氨基苯甲酸酯和烟酸酯。
