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
