STUDIES ON SPIROHETEROCYCLES : SYNTHESIS OF NEW SPIRO 4- THIAZOLIDINONES AS POSSIBLE BIODYNAMICS

Abstract
Spiro-4- thiazolidinones have been synthesized by the cyclocondensation of
phthalazinyl hydrazones with cyclic ketones and substituted mercapto acetic acids.
Compounds were screened for their antibacterial, antifungal and antihypertensive
activity. The combined elemental analyses and spectroscopic data prove the
authenticity of the synthesized compounds
