The newly synthesized compounds were characterized by the spectroscopic tools IR, 1H‐NMR, 13C‐NMR, MS, and elemental analysis. Some of these compounds have been screened in vitro for antimicrobial activity against different strains of bacteria and fungi and also were tested against two cancer cell lines: mammary gland breast cancer (MCF‐7) and colon cancer (HCT‐118).
在常规方法和微波方法下,都合成了2-氨基-4 H-吡喃-3-腈衍生物1并与不同的试剂反应。因此,用氯乙酰氯,异氰酸苯酯,异氰酸苯酯,氰基乙酸,苯甲酰氯,原甲酸三乙酯,乙酸酐/ H 2 SO 4,亚芳基丙二腈,尿素和/或p处理了2-氨基-4 H-吡喃-3-腈的衍生物。分别产生氨基磺基胍的氯乙酰胺,3-苯基脲,氰基乙酰胺,N-苯甲酰吡喃,甲酸乙酯,吡喃并嘧啶-4-酮,吡喃并吡啶,吡喃并嘧啶-2-酮和吡喃并嘧啶-2-亚胺衍生物。同时,化合物1与溴乙酸乙酯,苯甲酰溴,邻苯二甲酸酐,不同的芳族胺和/或乙酸/ H 2 SO 4反应生成5-氨基吡喃并[2,3- b ]吡咯-6-羧酸根,二氢吡喃并[2,3- b ]吡咯-6-基(苯基)甲酮,1,3-二氧代异吲哚基吡喃,1,4-二氢吡啶和2-羟基-1,4-二氢吡啶衍生物。另一方面,当化合物1与马来酸酐和/或水合肼反应时,分别获得了吡喃-4-氧代丁-2-烯酸和
