Owing to hindered diffusions, the application of porous catalytic materials has been limited to relatively simple organic transformations with small substrates. Herein we report a dimensional reduction strategy to construct a two-dimensional metal-organic framework (MOF), Zr6OTf-BTB, with 96% accessible Lewis acidic sites as probed by the bulky Lewis base pivalonitrile. With nearly free substrate accessibility, Zr6OTf-BTB outperformed two three-dimensional MOF counterparts of similar Lewis acidity (Zr6OTf-BPDC and Zr6OTf-BTC) in catalyzing sterically hindered multicomponent reactions (MCRs) for the construction of tetrahydroquinoline and aziridine carboxylate derivatives with high turnover numbers (TONs). Zr6OTf-BTB was also superior to the homogeneous benchmark Sc(OTf)(3) with nearly 14 times higher TON and 9 times longer catalyst lifetime. Furthermore, the topology-activity relationships in these Zr-based Lewis acidic MOFs were rationalized by comparing their Lewis acidity, numbers of Lewis acidic sites, and sterically accessible Lewis acidic sites. Zr6OTf-BTB was successfully used to construct several bioactive molecules via MCRs with excellent efficiency. This dimensional reduction strategy should allow the development of other MOF catalysts for synthetically useful and complicated organic transformations.

SDS of cas: 100-51-6. I found the field of Pharmacology & Pharmacy very interesting. Saw the article Design, Synthesis, and Biological Evaluation of Imidazopyridines as PD-1/PD-L1 Antagonists published in 2021.0, Reprint Addresses Domling, A (corresponding author), Univ Groningen, Dept Drug Design, NL-9713 AV Groningen, Netherlands.. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol.

The PD-1/PD-L1 axis has proven to be a highly efficacious target for cancer immune checkpoint therapy with several approved antibodies. Also, small molecules based on a biphenyl core can antagonize PD-1/PD-L1, leading to the in vitro formation of PD-L1 dimers. However, their development remains challenging, as we do not yet fully understand their mode of action. In this work, we designed a new scaffold based on our previously solved high-resolution structures of low-molecular-weight inhibitors bound to PD-L1. A small compound library was synthesized using the Groebke-Blackburn-Bienayme multicomponent reaction (GBB-3CR), resulting in the structure-activity relationship of imidazo[1,2-a]pyridine-based inhibitors. These inhibitors were tested for their biological activity using various biophysical assays giving potent candidates with low-micromolar PD-L1 affinities. An obtained PD-L1 cocrystal structure reveals the binding to PD-L1. Our results open the door to an interesting bioactive scaffold that could lead to a new class of PD-L1 antagonists.

This communication describes the palladium-catalyzed reductive carbonylation of aryl fluorosulfonates (ArOSO2F) using syngas as an inexpensive and sustainable source of carbon monoxide and hydrogen. The conversion of phenols to aryl fluorosulfonates can be conveniently achieved by employing the inexpensive commodity chemical sulfuryl fluoride (SO2F2) and base. The developed continuous flow formylation protocol requires relatively low loadings for palladium acetate (1.25 mol%) and ligand (2.5 mol%). Good to excellent yields of aryl aldehydes were obtained within 45 min for substrates containing electron withdrawing substituents, and 2 h for substrates containing electron donating substituents. The optimal reaction conditions were identified as 120 degrees C temperature and 20 bar pressure in dimethyl sulfoxide (DMSO) as solvent. DMSO was crucial in suppressing Pd black formation and enhancing reaction rate and selectivity.

A direct oxidative esterification of alpha-amino carbonyl compounds by two kinds of hydroperoxides, for the synthesis of alpha-keto esters has been developed. The reaction shows broad substrates scope and good functional group tolerance, even for the synthesis of bulkyl esters, and is free of metal catalysts and external additives.

I found the field of Chemistry very interesting. Saw the article General Paradigm in Photoredox Nickel-Catalyzed Cross-Coupling Allows for Light-Free Access to Reactivity published in 2020.

Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone

Self-sustained Ni-I/III cycles are established as a potentially general paradigm in photoredox Ni-catalyzed carbon-heteroatom cross-coupling reactions through a strategy that allows us to recapitulate photoredox-like reactivity in the absence of light across a wide range of substrates in the amination, etherification, and esterification of aryl bromides, the latter of which has remained, hitherto, elusive under thermal Ni catalysis. Moreover, the accessibility of esterification in the absence of light is especially notable because previous mechanistic studies on this transformation under photoredox conditions have unanimously invoked energy-transfer-mediated pathways.

RTILs exhibit supramolecular self-assembled polymeric aggregation due to noncovalent interactions. The influence of the aggregation behaviour of RTILs on catalytic activity is evident but still poorly understood. The present work focuses on establishing a relationship between the role of supramolecular self-assembly of RTILs on catalysis in organic reactions. Herein, we report four unreported, air and water stable, halide free, C-2-symmetrical, third generation, hydrophobic imidazolium-based room temperature ionic liquids (RTILs 1-4), their synthesis and function as catalysts for the synthesis of 4H-chromene derivatives (terahydrobenzo[b]pyran) and Knoevenagel condensation. The RTILs showed unprecedented solubility/miscibility behaviour. The RilLs showed that 1,3-dihexyhmidazolium 2-aminobenzoate [hhim] [OAB] (RTIL-3) performed better in terms of yield and reaction time. Supramolecular polymeric aggregation was explored by employing ESIMS, while the critical aggregation concentration (CAC) was calculated via recording electrical conductivity of RTILs in absolute ethanol. We have also used rheometry experiments to explore forces governing the occurrence of aggregates in the liquid phase of RTILs. (C) 2020 Elsevier B.V. All rights reserved.

The well-defined cavities of metal-organic frameworks (MOFs) offer interesting opportunities for the encapsulation of various nanoparticles, organic dyes and metal complexes. In particular, [Ru(bpy)(3)](2+)-incorporated MOFs (bpy = 2,2-bipyridine) have been studied because of the high photocatalytic activity of the Ru complex. However, the successful application of this composite in photocatalysis is rarely reported. We herein report the facile encapsulation of [Ru(bpy)(3)](2+) in MIL-125-NH2, an MOF composed of 2-aminoterephthalic acid linkers and Ti8O8(OH)(4) clusters. The Ru complex-incorporated MOF showed significantly enhanced activity in the photocatalytic aerobic oxidation of benzylalcohol to benzaldehyde as compared to its complex-free and amine-free counterparts. The high activity of the metal complex-incorporated MOF was attributed to the combined visible light absorption by both MIL-125-NH2 and the [Ru(bpy)(3)](2+) complex.

Readily available acrylamide naphthoquinones can be converted into the corresponding aza-anthraquinones using 6 pi-photoelectrocyclization reactions. Not only do these reactions not proceed thermally but, as demonstrated here, they can also be used to generate a range of aza-anthraquinone and aza-tetracycline derivatives including the natural products griffithazanone A and marcanine A. Several of the aza-anthraquinones generated in this work showed antibacterial activity.
