A novel series of flavazoles 3a-1 were synthesized via dehydrative cyclization of a new series of 3-[(α-arylhydrazono)-aroylmethyl]quinoxalin-2(1H)-ones 2a-1 and their biologicalactivity has been evaluated. The tautomeric structure of the precursors 2a-1 has also been elucidated.
一种新型系列flavazoles 3A-1的合成通过一个新的系列的第3的脱水闭环- [(α-芳基亚肼基)-aroylmethyl]喹喔啉-2(1 H ^) -酮2A-1和它们的生物活性进行了评估。前体2a-1的互变异构结构也已经阐明。
