4‐triazole‐5(4H)‐thione hybrids 6a – 6o was designed, synthesized and evaluated for their in vitro antibacterial activities against a panel of clinically important drug‐sensitive and drug‐resistant Gram‐positive and Gram‐negative pathogens. Our results revealed that all hybrids 6a – 6o had great potency against the tested strains, especially Gram‐negative pathogens. The synthesized hybrids were more potent

irradiation as well as by a classical method. The beneficial effect of microwave irradiation on the dehydrative cyclization of thiosemicarbazides in different reaction media is described. Our results show that the effect of microwave irradiation on the reaction studied was the shortening of reaction times (from 2–9 h to 2–4 min) and a minor decrease (1–4%) in yields. The structure of the new compounds was

Herein, we report on the preparation of a library of 5-substituted-2-amino-1,3,4-oxadiazoles and the corresponding thiadiazole analogues. Presented is a one-pot preparation of the 2-ammosulfonylated analogues through a three component coupling of an acylhydrazine, an isocyanate and sulfonyl chloride promoted by a polymer-supported phosphazine base under microwave dielectric heating. Also described is the optimization process and details pertaining to the elucidation of the reaction products. (c) 2005 Elsevier Ltd. All rights reserved.
