Synthesis of new pyrazolothiazole derivatives from 4-thiazolidinones.
The synthesis of new 2,3,5,6-aryl substituted tetrahydro-2H-pyrazolo[3,4-d]- thiazoles 4a-j as potential biologically active compounds by the cyclocondensation of phenyl hydrazine with new 5-arylidene derivatives 2a-j of 2,3-disubstituted-1,3- thiazolidin-4-ones 1a-e is reported.
متن کاملBetaine hydrochloride (BHC) catalyzed synthesis of 4-thiazolidinones derivatives
Betaine hydrochloride (BHC), as an ionic salt was found to be an efficient and recyclable catalyst for the one-pot synthesis of 4-thiazolidinediones. The methodology of study was achieved by one-pot condensation of aromatic aldehydes, aromatic amine and mercaptoacetic acid in the presence of betaine hydrochloride (BHC) at reflux temperature in ethanol as solvent. The efficiency of Betaine hydro...

متن کاملSTUDIES ON SPIROHETEROCYCLES : SYNTHESIS OF NEW SPIRO 4- THIAZOLIDINONES AS POSSIBLE BIODYNAMICS
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
متن کاملSynthesis of New Pyridine Based 4-Thiazolidinones Incorporated Benzothiazoles and Evaluation of Their Antimicrobial Activity
Substituted Schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (Ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. On cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...
