Metalation of CH2OH-substituted triazolium salts with CoCl2 under basic conditions affords C,O-bidentate chelating carbene Co(III) complexes (3a, 3b), while analogous phenyl-substituted produce monodentate Co(II) (3c, 3d). The distinct substituent-induced properties the metal centers were demonstrated by electrochemical measurements and catalytic activities in two specific processes. showed app...
the aim of this research is to study ni2+ supported on hydroxyapatite-core-shell magnetic γ-fe2o3 nanoparticles (γ-fe2o3@hap-ni2+) as a green and recyclable catalyst for the biginelli reaction under solvent-free conditions. one-pot multi-component condensation of 1,3-dicarbonyl compounds, urea and aldehydes at 80 oc affords the corresponding compounds in high yields and in short reaction times ...
We present a self-organizing map (SOM) approach to predicting macromolecular targets for combinatorial compound libraries. The aim was to study the usefulness of the SOM in combination with a topological pharmacophore representation (CATS) for selecting biologically active compounds from a virtual combinatorial compound collection, taking the multi-component Biginelli dihydropyrimidine reaction...
In order to develop a better bioactive molecules with good efficacy, we synthesized a new series of Thiazolo [3,2-a] pyrimidine derivatives with good yield and studied their anthelmintic properties, structureactivity relationships (SARs). A new series of Thiazolo[3,2-a]pyrimidines have been synthesized through duff formylation, ‘One pot’ Biginelli reaction, cyclization followed by knoevenagel c...
Dioxidovanadium(V) complex [VVO2(sal-aebmz)] (1) (where Hsal-aebmz = Schiff base derived from the condensation of salicylaldehyde and 2-aminoethylbenzimidazole) has been immobilized on chloromethylated polystyrene (PS-Cl) cross-linked with divinylbenzene to obtain [VVO2(sal-aebmz)]@PS (2), a heterogeneous complex. Both complexes, after characterization, have used as catalysts explore single pot...
