Abstract
Dropwise addition of alpha -bromo ketoximes to a solution of KCN in MeOH at room temperature gave 5-amino-3-arylisoxazoles in moderate to good yields. Treatment of the isoxazoles prepared with tetrasulfur tetranitride antimony (V) chloride complex (S4N4. SbCl5) in toluene at 100 degreesC afforded novel 3-aryl-1,2,5-thiadiazole-4-carboxamides.
