into isatinylidenes (7,9–13, 17–19) by dehydration with 4‐toluenesulfonic acid. The dimer‐type compounds (14, 20) were also isolated in a few cases. The obtained isatinylidenes were transformed into 3‐spiro‐cyclopropane‐oxindoles (21–32) with dimethyloxosulfonium methylide. Compound 22 shows protective effects against hypobaric hypoxia and triethyltin induced brain edema.
羟基吲哚酮 (1-6, 15-16) 通过用 4-甲苯磺酸脱水转化为靛红 (7,9-13, 17-19)。在少数情况下也分离出二聚体型化合物 (14, 20)。将获得的靛红转化为 3-螺-环丙烷-羟吲哚(21-32)与二甲基氧锍甲基化物。化合物 22 显示出对低压缺氧和三乙基锡诱导的脑水肿的保护作用。
