readily available indole-7-glyoxyloylchlorides and 7-trichloroacetylindoles and underwent cyclodehydration to produce 2,5-di(7-indolyl)-1,3,4-oxadiazoles and a 2,2′-bi-1,3,4-oxadiazolyl with phosphoryl chloride in ethyl acetate. This efficient protocol was subsequently used for the synthesis of 2- and 7-indolyl 2-(1,3,4-thiadiazolyl)ketones from related indolyl-hydrazine carbothioamides. The synthesised
从容易获得的吲哚-7-乙二酰氯和7-三氯乙酰吲哚制备了一系列新型的肼桥联双吲哚,然后进行环脱水以生产2,5-二(7-吲哚基)-1,3,4-恶二唑和2, 2'-bi-1,3,4-恶二唑基与磷酰氯的乙酸乙酯溶液。该有效方案随后用于由相关的吲哚基-肼甲硫基酰胺合成2-和7-吲哚基2-(1,3,4-噻二唑基)酮。评估了合成的双吲哚的抗菌特性,特别是抑制RNA聚合酶和σ因子之间的蛋白质-蛋白质复合物形成及其对革兰氏阳性枯草芽孢杆菌和革兰氏阴性大肠杆菌的杀菌作用。
