2-(methylaminoacetyl)quinolines (2) and 2-methyl-1H-pyrrolo[3,4-b]quinolin-3(2H)-ones (3) by irradiation in a nitrogen atmosphere. The reaction was quite efficient in acetonitrile but inefficient in hydrocarbon solvents and ethanol. The introduction of a chlorine atom to the 4-position of a quinoline nucleus caused an increase of the yield of 3 in company with a decrease of the yield of 2. On the other
2-(二甲基氨基甲酰基)喹啉在氮气氛中通过辐照转化为2-(甲基氨基乙酰基)喹啉(2)和2-甲基-1H-吡咯并[3,4-b]喹啉-3(2H)-酮(3) . 该反应在乙腈中非常有效,但在烃类溶剂和乙醇中效率低下。在喹啉核的 4-位引入氯原子导致 3 的产率增加,2 的产率降低。 另一方面,在氧气氛中照射得到 2-(甲基氨基甲酰基)喹啉为主要产品,但 2 和 3 为次要产品。淬灭和敏化实验的结果证实,三重态 π,π* 状态是这些产物形成的原因。
