Synthesis, characterization, and molecular docking of benzodiazepines in the presence of SrFe12O19 magnetic nanocatalyst

Synthetic aspects of 1,4- and 1,5-benzodiazepines usingo-phenylenediamine: a study of past quinquennial

“…Ahmadi et al 78 discovered a green and signicant method for the synthesis of 1,5-BZDs (23) using OPDs (1), dimedone (21b) and aldehydes (22) with SrFe 12 O 19 as a magnetic solid nanocatalyst under solvent-free conditions. The catalyst was prepared by a sol-gel auto combustion method using Fe(NO 3 ) 3 $9H 2 O and Sr(NO 3 ) 3 powder and has many benets such as reusable, easy recovery, high activity and easy handling.…”

Immobilized nickel boride nanoparticles on magnetic functionalized multi-walled carbon nanotubes: a new nanocomposite for the efficient one-pot synthesis of 1,4-benzodiazepines

“…In recent years, extensive investigations have been devoted to exploring the applicability of one-pot multicomponent reactions (MCRs) in the development of facile, straightforward, and highly efficient methodologies for the synthesis of a broad range of 1,4-benzodiazepines. 18 Among them, a number of catalytic systems and methodologies for the synthesis of 1,4-benzodiazepines based on the condensation of o -phenylenediamine with dimedone and various aldehydes, each of which holds a unique position in the synthesis of heterocyclic compounds, have been reported by researchers, such as UiO-66 MOF, 31 La 2 O 3 /La(OH) 3 , 33 GO nanosheets, 34 Gr@TiO 2 NCs, 35 Cu( ii )/PI-COF, 36 acetic acid/water under microwave irradiation, 37 sulfated polyborate, 38 B(HSO 4 ) 3 , 39 l -proline, 40 CuFe 2 O 4 , 41 Fe(OTs) 3 /SiO 2 , 42 CoFe 2 O 4 @GO-K22, 43 CoFe 2 O 4 @SiO 2 @NH-NH 2 -PCuW, 44 CeO 2 /CuO@GQDs@NH 2 , 45 [H-PFBA][PF 6 ], 46 [H-NMP][HSO 4 ], 47 ZnS nanoparticles, 48 Fe 3 O 4 @chitosan, 49 Fe( iii )-NicTC@nSiO 2 , 50 SrFe 12 O 19 , 51 chitosan functionalized by triacid imide, 52 HBF 4 –SiO 2 , 53 SPINOL-derived chiral phosphoric acid, 54 and oxalic acid. 55 Although each of these methods has its own advantages, they also have several shortcomings that need to be addressed.…”

Synergistic effect of GO/SrFe12O19 as magnetic hybrid nanocatalyst for regioselective ring-opening of epoxides with amines under eco-friendly conditions

“…[7][8][9][10][11][12] Among the interesting nanomaterials, hexagonal ferrites represent important classes of magnetic materials in diverse areas of applications such as plastic magnets, permanent magnets, recording media, microwave components, high-frequency devices, and catalysts or photocatalysts. [13][14][15][16] Since their discovery in the 1950s there has been an increasing degree of interest in the hexagonal ferrites, 17 and their synthesis and study deserve a particular interest for R&D researchers. 16,[18][19][20] However, magnetic nanoparticles (MNPs) have gained the attention of many scientists due to their excellent physical and chemical properties compared to traditional bulk materials, such as superparamagnetism, high surface area, high surfaceto-volume ratio, simple separation under external magnetic elds, and high adsorption capacity.…”
