The preparation of bis-thiazolidinones has been achieved by a one-pot condensation reaction of araldehydes, ethylenediamine, and 2-mercaptoacetic acid in the presence of nano-CuFe2O4@chitosan under reflux conditions in toluene. The c

The catalytic potential of various protic acids has been assessed for the one pot tandem condensation-cyclisation reaction involving an aldehyde, an amine, and thioglycolic acid to form 2,3-disubstituted thiazolidin-4-ones. The catalytic potential of the various protic acids that follows the order TfOH > HClO4 > H2SO4 ~ p-TsOH > MsOH ~ HBF4 > TFA ~ AcOH is improved significantly by adsorption on solid supports, in particular using silica gel (230-400 mesh size), with the resulting relative catalytic potential following the order HClO 4-SiO2 > TfOH-SiO2 ? H2SO 4-SiO2 > p-TsOH-SiO2 > MsOH-SiO 2 ~ HBF4-SiO2 > TFA-SiO2 ~ HOAc-SiO2. The better catalytic potential of HClO 4-SiO2 as compared to that of Tf-SiO2, although TfOH is a stronger protic acid than HClO4, can be rationalised through a transition state model depicting the interaction of the individual protic acid with SiO2. The catalytic efficiency of HClO4 adsorbed on various solid supports was in the order HClO4-SiO 2 ? HClO4-K10 > HClO4-KSF > HClO 4-TiO2 ~ HClO4-Al2O3. The catalytic system HClO4-SiO2 is compatible with different variations of aldehydes (aryl/heteroaryl/alkyl/cycloalkyl) and the amines (aryl/heteroaryl/arylalkyl/alkyl/cycloalkyl) affording the desired 2,3-disubstituted thiazolidin-4-ones in 70-87% yields (43 examples). The electronic and the steric factors associated with the aldehydes and the amines provide a handle for selective thiazolidinone formation and were found to be dependent on the extent of imine formation. No significant amount of thiazolidinone formation took place during the reaction of the preformed amide (synthesised from the amine and thioglycolic acid) with benzaldehyde suggesting that the reaction proceeds through the initial reversible imine formation followed by cyclocondensation of the preformed imine with thioglycolic acid, the reversible imine formation being the determining step to control selectivity of thiazolidinone formation in competitive environments. The feasibility of a large scale reaction and catalyst recycling/reuse is demonstrated.

New α,ω-bis-(2-hetaryl-4-oxothiazolidin-3-yl)alkanes were prepared via a common two step procedure using N,N-bis-hetarylidenamines condensation with α-mercaptoacetic acid. The used bis-aldimines were obtained from reaction between ethylenediamine or putrescine and benzaldehyde or the isomeric pyridinecarboxyaldehydes. The bis-(2-phenyl-4-oxothiazolidin-3-yl) alkanes were prepared by one-pot three component reaction of diamine, aldehyde and α-mercaptoacetic acid under very mild conditions.

Several new 3,3'-bisthiazolidinones (III) and 2,2-disubstituted thiazolidinones (VIII) have been synthesised by the cycloadditive dehydration of thioglycolic acid to the azomethin derivatives (II) and (VII) prepared from the aliphatic diamines and heterocyclic monoamines respectively.The structure of the compounds have been confirmed from the spectral data and elemental analysis.The fungicidal and bactericidal activities of the compounds have also been evaluated.
