Synthesis of chromones and pyrazolines as antimicrobial & antifungal agents

A series of chromones and pyrazolines have been synthesized and evaluated for their antimicrobial and antifungal activity against Gram+ve and Gram-ve microorganisms. 2-Hydroxy acetophenone on treatment with substituted aldehydes gave the corresponding cha

Microwave induced synthesis and anti microbial activities of some [3-(2-hydroxyphenyl)-5-aryl-2-pyrazolinyl]-4-thiazolidenones

A series of new [3-(2-hydroxyphenyl)-5-aryl-2-pyrazolinyi]-4- thiazolidenones (4a-g.) has been prepared by microwave irradiation technique. O-hydroxy chalcones (1) were treated with hydrazine hydrate to afford corresponding pyrazolines (2) which were trea

Oxidation of Pyrazolines with Manganese Dioxide

Pyrazolines have been oxidised with manganese dioxide in chloroform at room temperature to give pyrazoles in good yields.
