Oxidation of 3 afforded pyrazole derivatives 4. Benzenesulfonylureas 5 and thioureas 6 were also prepared. Cyclization of the thioureido group of compounds 6 by treating with ethyl bromoacetate, ethyl beta-bromopropionate and alpha-bromoacetophenone afforded the corresponding thiazolidinone, thiazinone and thiazoline derivatives 7, 8, 9 respectively, The biological activity of the prepared compounds were also studied.  Journal Name : Source: INDIAN JOURNAL OF HETEROCYCLIC CHEMISTRY  Volume : 6  Issue Number : 1  Publishing Year : 1996 AH   Added Date : Saturday, June 14, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email سالم أحمد باسيف   Researcher     Back To Researches Page
