A novel approach for synthesis of 3-amino-5-aryl-2,5-dihydropyridazines using onium salt as soluble support

In this work it was presented an application of task specific onium salt as soluble support for the synthesis of 3-amino-5-aryl-2,5-dihydropyridazines. This soluble support is of wide applicability and combines advantages of solid phase synthesis without its limitations with those of solution phase chemistry. After a simple washing step, products were cleaved from the supports and obtained in good yields.
