Synthesis and biological activity of some novel pyrazolines
Chalcones were prepared from substituted acetophenones and substituted benzaldehydes and condensed with hydrazine hydrate in ethanol to get the corresponding pyrazolines (Pdc1 to Pdc 14). The compounds were synthesized and characterizes by TLC, melting po
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
