MICROWAVE ASSISTED SYNTHESIS & QSAR STUDY OF SOME NOVEL PYRAZOLYL THIAZINE DERIVATIVES
AbstractThis work involves synthesis of pyrazolyl thiazine derivatives from different chalcones [1(a-b)] synthesized from substituted acetophenones and different aromatic aldehydes in basic medium by Claisen-Schmidt reaction. These chalcones [1(a-b)] on condensation with different hydrazides [2(a-b)] and isothiocyanates [3(a-b)] when irradiated with microwaves (20%, 140watts) in scientific microwave oven, give different 2-phenyl-2,5-dihydro-pyrazole-1-carbothioic acid phenyl amide derivatives [4(a-g)] which on further MW assisted condensation with substituted acetophenones and different aromatic aldehydes, furnish pyrazolyl thiazine derivatives [7(a-j)]. Library of such pyrazolyl thiazine derivatives has been generated and the structures were subjected to PASS for their probabilities of being active biologically. QSAR study of the library was done to find out most active Molecules.
