A Novel Route to Acyl Ureas: Syntheses of N-[5-(2-Chlorophenyl)-2-Furoyl]-N'-Arylthioureas and Ureas
摘要:
A novel route to acyl ureas is described. Reaction of 5-(2-chlorophenyl)-2-furoyl chloride with ammonium thiocyanate first, then arylamine under phase transfer catalysis gives N-[5-(2-chlorophenyl)-2-furoyl]-N'-aryl-thioureas (1a-o). Compounds 1a-o on oxidation with potassium iodate respectively under reflux result in the formation of N-[5-(2-chlorophenyl)-2-furoyl-N'-arylureas (2a-o).
