A series of 40 derivatives of the [1,2]oxazolo[5,4-e]indazoles ring system have been prepared with good yields using a versatile and convenient route. Annelation of the [1,2]oxazole ring on the indazole-4-one system was achieved by reaction of the corresponding enaminoketones with hydroxylamine hydrochloride. Derivatives of the title ring system were tested by the National Cancer Institute of Bethesda
使用通用且方便的途径,已经以良好的收率制备了[1,2]恶唑并[5,4- e ]吲唑环系的一系列40种衍生物。通过使相应的烯胺酮与盐酸羟胺反应,可以使吲唑-4-一酮体系上的[1,2]恶唑环退火。美国贝塞斯达国家癌症研究所对标题环系统的衍生物进行了测试,其中一种(13吨)在低微摩尔浓度下显示出对所有54种人类肿瘤细胞系的生长抑制活性。
