Abstract:

Pyrazoles are a class of heterocycles with five members, containing two atoms of nitrogen in adjacent positions. Diverse ranges of biological properties are associated with these molecules, including antimicrobial, antitumor, anti-inflammatory, antiviral, anticonvulsant and antidepressant activities. The current situation of environmental degradation demands from the chemical community the development of more efficient and cleaner methodologies in regard to energy consumption and reduction of waste. In agreement with this demand, we prepared several classes of heterocyclic compounds by non-conventional methods such as microwaves and sonochemistry. The success of microwave technology is based on the dipole rotation, which is responsible for heating the substances efficiently, occurring directly in the molecules. In this work, we report the synthesis of pyrazoles derivated from chalcones under microwave irradiation
