DEVELOPMENT OF NEW ACCESS ROUTES TO PYRAZOLO[1,5-a]PYRIMIDINE USING 4-HYDROXY-6-METHYLPYRAN-2-ONE

Abstract

In this work, we propose a new and fast strategy giving the pyrazolo[1,5-a]pyrimidines substituted at positions 5 and 7 via condensation of 3-amino-5-arylpyrazoles with 2-hydroxy-6-methylpyran-2-one in both conventional heating and microwave irradiation.
