AbstractCondensation of 2-acetylpyrrole with 5-methylfuran-2-carboxyaldehyde and 4-chlorobenzaldehyde in 20% NaOH give the corresponding 2-chalconylpyrroles. Some new 2-alkoxy-3-cyano-4,6-diarylpyridines were synthesized by condensation of chalcones with malononitrile, followed by cyclization in sodium alkoxide. The reactivity of chalcones towards nitrogen nucleophiles such as thiourea and hydroxylamine
摘要2-乙酰基吡咯与5-甲基呋喃-2-羧醛和4-氯苯甲醛在20%NaOH中的缩合反应得到相应的2-邻苯二甲酰基吡咯。通过查耳酮与丙二腈缩合,然后在醇钠中环化,合成了一些新的2-烷氧基-3-氰基-4,6-二芳基吡啶。朝氮亲核试剂,如硫脲和盐酸羟胺,以提供硫代嘧啶查耳酮的反应性小号和异恶唑啉进行了研究。 图形概要
