compounds in the synthesis of tryptamine, serotonin [22, 23] and biolo#cally active polymethine dyes [24] stimulated further search for the biolo#cally active compounds among the 3substituted hydroxyindoles [16, 25]. It was reported that some 3-methylene-2-indolones can be obtained by the Wittig reaction between isatins and methylenetriphenylphosphoranes [5, 13, 15, 22, 26, 27]. Judgflag from the published
众所周知,3-酰基亚甲基-2-吲哚酮可作为初始化合物,通过与链二烯的狄尔斯-阿尔德反应获得羟基吲哚的各种3-螺环衍生物[I, 2]。3-酰基亚甲基-2-吲哚酮与各种CH活化的羰基化合物[3, 4]和烯胺[5]发生迈克尔反应,并与硫脲、苯硫脲等亲核试剂缩合,形成具有紧密结构的类似化合物-3-螺吲哚酮[6] 和水合肼 [4, 7]。3-苯甲酰基亚甲基羟基吲哚在与 1,3-偶极偶氮甲亚胺内酯的反应中用作偶极试剂 [8, 9]。还描述了 3-酰基亚甲基-2-吲哚酮在肼和苯肼作用下的杂环化反应 [4, 7, I 0] 和在酸性介质中将 3-芳酰基亚甲基-2-吲哚酮再环化为 2-芳基辛可宁酸的衍生物 [11, 12] 具有滞后抗病毒活性 [11]。然而,由于缺乏用于合成一些 3-aylmethylene-2-indolones(例如,具有 3-aldoxycarbonyl 的那些)的方便的制备方法,使得这类化合物难以获得
