Methyl 1-acetylenyl-9,10-anthraquinone-2-carboxylates react with NH2NH2 in ethanol at 80°C to give commensurable amounts of substituted 7H-dibenzo[de,h]quinolin-7-ones and 3,4-dihydro-3-aminonaphtho[2,3-f]isoquinoline-4,7,12-triones. The main, route of the reaction apparently includes nucleophilic addition of the reagent to the triple bond of the ester followed by intramolecular cyclization of the
1-乙炔基-9,10-蒽醌-2-羧酸甲酯在 80°C 的乙醇中与 NH2NH2 反应,生成相当数量的取代 7H-二苯并[de,h]quinolin-7-ones 和 3,4-dihydro-3 -aminonaphtho[2,3-f]isoquinoline-4,7,12-triones。反应的主要途径显然包括将试剂亲核加成到酯的三键上,然后加合物与所涉及的羰基或甲氧基羰基进行分子内环化。
