Synthesis of 2-(N-formyl)-5-aryl/aryloxymethyl-1,3,4-thiadiazoles with potential bioactivity in PEG-400
摘要:
An environmental benign procedure for synthesis of 2-(N-formyl)-5-aryl/aryloxymethyl-1,3,4-thiadiazoles has been developed by reaction of 2-amino-5-aryl/aryloxymethyl-1,3,4-thiadiazoles with formic acid in PEG-400. The key advantages of this protocol are the shorter reaction time, higher yields, lower cost, simple workup, and environment-friendly compared to conventional organic solvent reaction. The present method does not involve any hazardous organic solvent or catalyst. (C) 2009 Xi Cun Wang. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
