## Abstract A simple and efficient method has been developed for the synthesis of various pyrazolo[3,4β__d__]pyrimidines by using microwave irradiation under solventβfree conditions. The advantages of applying microwave irradiation compared with the classical method were demonstrated. The structure
Pyrazolo[3,4-b]quinolines and pyrazolo[3,4-c]pyrazoles have been synthesized from b-chlorovinylaldehydes and hydrazine hydrate/phenylhydrazine using p-TsOH under microwave irradiation.
