Amidoalkyl Naphthols as Important Bioactive Substances and Building Blocks: A Review on the Current Catalytic Mannich-Type Synthetic Approaches

“…The recent literature precedents are summarized in Table 3, Refs. [73][74][75][76][77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92].…”

“…However, this catalyst required the use of refluxing ethanol as a reaction medium [88]. CdCl 2 -containing filamentous silica nanoparticles [89] and CuFe 2 O 4 /KCC-1/PMA [90] also provided access to very high yields of a similar scope to amidoalkyl naphthols. In comparison with the bifunctional SBA-amino-amido-carboxylic acid, these catalysts operated under solvent-free conditions and lower catalyst loadings.…”

Synthesis of ZIF-8/ZnFe2O4/GO-OSO3H nanocomposite as a superior and reusable heterogeneous catalyst for the preparation of pyrimidine derivatives and investigation of their antimicrobial activities

“…The incorporation of the merits of MOFs and GO to construct a novel class of composites with both enhanced functionality and large surface area is of great significance and interest. Recently, nanotechnology with a wide diversity of nanomaterials has created a new revolution in science and especially in chemical fields [ [43] , [44] , [45] , [46] , [47] , [48] ].…”

Stabilization of Pd NPs over the surface of β-cyclodextrin incorporated UiO-66-NH2 for the C–C coupling reaction

“…12,13 Also b-cyclodextrin can activate variety of organic compounds like aldehydes, ketones, anhydride, oximes, amines, nitriles and increase the rate of reactions. 14,15 Here, novel b-cyclodextrin (b-CD)@1,4-dibromo butane@functionalized UiO-66-NH 2 /Pd-NPs composite was in situ prepared using b-CD functionalized MOF (Zr) and Pd-NPs, and C-C coupling reactions to promote formation coupling desired was developed based on the composite. A series of investigations on the b-cyclodextrin (b-CD)@1,4-dibromo butane@functionalized UiO-66-NH 2 /Pd-NPs composite material were conducted.…”

“…[17][18][19] The tendency of the metal nanoparticle for aggregation in solvents makes it urgent to use heterogeneous supports for their cost-effective, green, and reusable applications. [12][13][14] The aggregation of metal NPs decreases their surface area, resulting in diminishing or even quenching the catalytic activities. Heterogenous supports not only can prevent aggregation of the NPs but can boost their catalytic performance or add some new features to the resulting composite.…”
