On July 31, 2014, Guo, Rongyun; Nie, Yao; Mu, Xiao Qing; Xu, Yan; Xiao, Rong published an article.Application In Synthesis of (R)-Methyl 3-hydroxybutanoate The title of the article was Genomic mining-based identification of novel stereospecific aldo-keto reductases toolbox from Candida parapsilosis for highly enantioselective reduction of carbonyl compounds. And the article contained the following:

Biocatalytic reduction of prochiral ketones offers significant potential in synthesis of optically active alcs. However, so far the application of aldo-keto reductases (AKRs) in asym. reduction has been hampered due to limited availability of AKRs with high enantioselectivity and catalytic efficiency. Based on the genome sequence of Candida parapsilosis, a versatile bioresource for asym. reduction, eight open reading frames encoding putative AKRs were discovered and expressed, and the resulted enzymes (CPARs), comprising an AKR toolbox, were evaluated toward various carbonyl substrates. The CPARs were active to the selected substrates, especially 2-hydroxyacetophenone and Et 4-chloro-3-oxobutyrate. Addnl., most of them were obviously enantioselective to the substrates and gave alc. products with optical purity up to 99% e.e. Of the enzymes, CPAR4 was outstanding with excellent enantioselectivity and broad substrate spectrum. All these pos. features demonstrate that genomic mining is powerful in searching for novel and efficient biocatalysts of desired reactions for pharmaceuticals and fine chems. synthesis. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Application In Synthesis of (R)-Methyl 3-hydroxybutanoate

On July 31, 2022, Li, Huai-Ming; Li, Guan-Dong; Li, Jun-Yu; Zhang, Teng published an article.SDS of cas: 1312703-30-2 The title of the article was An Iodine-Functionalized Metal-Organic framework for catalytic alkene bromination. And the article contained the following:

An iodine-functionalized metal-organic framework (MOF), UiO-68-I, was synthesized. UiO-68-I showed good catalytic activity for dibromination of alkenes and alkynes with a low catalyst loading of 1% and was able to be recycled and recovered efficiently. Mechanistic studies suggest that UiO-68-I may trigger the formation of mol. bromine through a radical intermediate and thus accelerate the reaction. The activity and stability of UiO-68-I outperforms most earlier reports on organoiodine catalysts, showing the great potential of iodine-functionalized MOFs as recyclable heterogeneous hypervalent iodine reagents or catalysts.

On August 3, 2020, Newar, Rajashree; Begum, Wahida; Antil, Neha; Shukla, Sakshi; Kumar, Ajay; Akhtar, Naved; Balendra; Manna, Kuntal published an article.Quality Control of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate The title of the article was Single-Site Cobalt-Catalyst Ligated with Pyridylimine-Functionalized Metal-Organic Frameworks for Arene and Benzylic Borylation. And the article contained the following:

A highly active single-site heterogeneous cobalt-catalyst is reported based on a porous and robust pyridylimine-functionalized metal-organic frameworks (pyrim-MOF) for chemoselective borylation of arene and benzylic C-H bonds. The pyrim-MOF having UiO-68 topol., constructed from zirconium-cluster secondary building units and pyridylimine-functionalized dicarboxylate bridging linkers, was metalated with CoCl2 followed by treatment of NaEt3BH to give the cobalt-functionalized MOF-catalyst (pyrim-MOF-Co). Pyrim-MOF-Co has a broad substrate scope, allowing the C-H borylation of halogen-, alkoxy-, alkyl-substituted arenes as well as heterocyclic ring systems using B2pin2 or HBpin (pin = pinacolate) as the borylating agent to afford the corresponding arene- or alkyl-boronate esters in good yields. Pyrim-MOF-Co gave a turnover number (TON) of up to 2500 and could be recycled and reused at least 9 times. Pyrim-MOF-Co was also significantly more robust and active than its homogeneous control, highlighting the beneficial effect of active-site isolation within the MOF framework that prevents intermol. decomposition The exptl. and computational studies suggested (pyrim•-)CoI(THF) as the active catalytic species within the MOF, which undergoes a mechanistic pathway of oxidative addition, turnover limiting σ-bond metathesis, followed by reductive elimination to afford the boronate ester. The pyridylimine-functionalized metal-organic framework (pyrim-MOF)-based single-site cobalt-catalyst is efficient for chemoselective borylation of arene and benzylic C-H bonds. The heterogeneous MOF-catalyst is significantly more robust and active than its homogeneous control, highlighting the beneficial effect of active-site isolation within the MOF framework that prevents intermol. decomposition The experimental process involved the reaction of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate(cas: 1312703-30-2).Quality Control of Dimethyl 2′-amino-[1,1′:4′,1”-terphenyl]-4,4”-dicarboxylate

Known hydrophilic halide salts of the title compounds are converted to new lipophilic BArf- (B(3,5-C6H3(CF3)2)4-) salts. These are isolated as hydrates (Λ- or Δ-[M(en)3]n+nBArf-·zH2O; z = 17-9) and characterized by NMR (acetone-d6) and microanalyses. Thermal stabilities are probed by capillary thermolyses and TGA and DSC measurements (onset of dehydration 71-151°C). In the presence of tertiary amines, they are effective catalysts for enantioselective Michael type carbon-carbon or carbon-nitrogen bond forming additions of 1,3-dicarbonyl compounds (acceptors: trans-β-nitrostyrene, di-tert-butylazodicarboxylate, 2-cyclopenten-1-one; average ee = 33%, 52%, 17%). Effects of the metal and charge upon enantioselectivities are analyzed. A number of properties appear to correlate to the NH Bronsted acidity order ([Pt(en)3]4+ > [Cr(en)3]3+ > [Co(en)3]3+ > [Rh(en)3]3+ > [Ir(en)3]3+).
