Synthesis and characterization of amino glucose-functionalized silica-coated NiFe₂O₄ nanoparticles: a heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of pyrano[3,2-c]chromen-5(4H)-ones

Abstract

We have developed NiFe2O4@SiO2@glucose amine as a new, mild and efficient avenue for the synthesis of pyrano[3,2-c]chromen-5(4H)-ones.

Copper/Schiff‐base complex immobilized on amine functionalized silica mesoporous magnetic nanoparticles under solvent‐free condition: A facile and new avenue for the synthesis of thiazolidin‐4‐ones

“…In continuation of our study to synthesize pharmaceutical compounds, [ 58–64 ] we used the nanoparticle KIT‐6‐NH 2 Schiff base complex in the multicomponent synthesis of 1,3‐thiazolidie‐4‐ones via the reaction between various aldehydes, thioglycolic acid, and 2‐aminobenzimidazole or amantadylamine (Scheme ).…”

Urazolium diacetate as a new, efficient and reusable Brønsted acid ionic liquid for the synthesis of novel derivatives of thiazolidine-4-ones

“…As a part of our previous interest towards the synthesize new heterocyclic and pharmaceutical compounds [42][43][44][45][46][47][48][49] and introduction new avenues and catalysts [50][51][52] in the organic transformations, here, we report a facile, green, new and efficient task specic ionic liquid urazolium diacetate for the synthesize novel thiazolidine-4-ones through three component reaction of various aldehydes, thioglycolic acid and 4-aminoazobenzene for the rst time.…”

Acetic acid catalysed solvent‐free synthesis of spiro‐isoxazolo[5,4‐b]pyridines/quinolines by mechano‐chemical grinding

“…With sustainable synthetic methodologies gaining impetus, solvent-free protocols for organic synthesis are becoming increasingly prevalent owing to their advantages of easy implementation, cleaner synthesis, and low cost. [15] To add to it, solvent free mechano-chemical approach of grinding is considered to be one of the favoured sustainable methods as it not only reduces the energy consumption but also expedites transformations in short reaction time. [16][17] In order to devise new synthetic strategies for heterocyclic compounds of pharmacological importance, in this study, we investigated the possibility of synthesising isoxazolo [5,4-b]pyridine/quinoline derivatives via one-pot three-component condensation of isatins, 3-methylisoxazol-5-amine and enolizable cyclic carbonyl compounds by solvent-free grinding method.…”
