Journal ArticleDOI
MnFe2O4@NH2@2AB-Ni: a novel, highly active, stable and magnetically recoverable nanocatalyst and use of this heterogeneous catalyst in green synthesis of spirooxindoles in water
TL;DR: In this paper, superparamagnetic manganese ferrite nanoparticles were synthesized following a co-precipitation method, and subsequently coated with 3-aminopropyltriethoxysilane (APTES) through a silanization reaction.
Journal ArticleDOI
One‐pot and three‐component synthesis of spiro[chromeno[2,3‐d] pyrimidine‐5,3′‐indoline]‐diones and spiro[chromeno[2,3‐c] pyrazole‐4,3′‐indoline]‐diones
TL;DR: A clean, one-pot and three-component synthesis of new spiro[chromeno[2,3d]pyrimidine-5,3-indoline]-2′,6(7H)-diones was reported in this paper.
Journal ArticleDOI
One-pot, three-component synthesis of spironaphthopyrano[2,3-d]pyrimidine-5,3′-indolines in water
TL;DR: A novel one-pot reaction between barbituric acids, isatins, and β-naphthol affords the previously unknown spiro compounds (IV) as mentioned in this paper.
Journal ArticleDOI
Inorganic-organic hybrid silica based tin complex as a novel, highly efficient and recyclable heterogeneous catalyst for the one-pot preparation of spirooxindoles in water.
TL;DR: A tin complex immobilized onsilica gel as a novel, green, highly efficient and heterogeneous reusable catalyst was synthesized by grafting 2-amino benzamide onto the silica gel surface as a result of the reaction between isatoic anhydride and 3-aminopropyl-functionalized silica Gel, followed by complexing with tin chloride.
Journal ArticleDOI
Effective surface modification of MnFe2O4@SiO2@PMIDA magnetic nanoparticles for rapid and high-density antibody immobilization
TL;DR: In this paper, superparamagnetic manganese ferrite nanoparticles were synthesized following co-precipitation method and then SiO2 shell was coated on the magnetic core with tetraethyl orthosilicate (TEOS) through a silanization reaction to prevent oxidation, agglomeration and increase the density of OH groups on the surface of MnFe2O4.
