Besides known reduction and solvent addition products, the photolysis of 1,3-dimethyluracil in methanol resulted in formation of the enamine 2-methoxycarbonyl-N-methyl-3-methylaminopropenamide (5) a novel ring-opening reaction. A mechanism for the formation of 5 is suggested and its structure was confirmed by an independent synthesis.
除了已知的还原和溶剂加成产物外,1,3-二甲基尿嘧啶在甲醇中的光解还导致烯胺2-甲氧基羰基-N-甲基-3-甲基氨基丙烯酰胺(5)的形成,这是一种新颖的开环反应。提出了形成5的机理,并通过独立的合成证实了其结构。
