  scaffolds in medicinal chemistry, the indole and 1,3,4‐oxadiazole ring systems, gave rise to 2‐arylamino‐5‐(3′‐indolyl)‐1,3,4‐oxadiazoles with IC50 values in the nanomolar range against a panel of tumor cell lines. Preliminary structure–activity relationship studies indicate potential for improved selectivity through further manipulation of the oxadiazole C‐2 and C‐5 positions.

  4-oxadiazole in excellent yields. The GSD studies of NMR spectra of aliphatic substrates (4di, 4dh) revealed the formation of three products, whereas, in the case of allylic and benzylic substrates, thiazolidinones were obtained as the sole products. Furthermore, to elucidate the plausible mechanism, DFT studies were performed affirming carbodiimide as the crucial intermediate for the interconversion of thiazolidinone

  A convenient one-pot method for the preparation of substituted 2-amino-1,3,4-oxadiazoles has been developed. The method is a significant improvement over previously reported syntheses. Reaction of carboxylic acids with thiosemicarbazides afforded the corresponding oxadiazoles in moderate to good yields. In general, the products precipitated from the reaction mixture, and were collected by filtration. In most of the cases, no chromatographic separations were required. To explore the scope and limitations of this reaction, various aliphatic, aromatic, and heteroaromatic carboxylic acids were reacted with different substituted thiosemicarbazides. The influence of R-1 and R-2 substituents on the reaction yield and additional results demonstrating the versatility of this method are presented. (c) 2008 Elsevier Ltd. All rights reserved.
