A highly regioselective, efficient, and metal-free oxidative cross dehydrogenative coupling (CDC) of aryl carbonyls with cyclic ethers has been developed. This method offers easy access to substituted alpha-arylated cyclic ethers with a high functional group tolerance in good to excellent yields. The regioselectivity of this CDC reaction was confirmed by density functional theory (DFT)-based calculations.

Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Sarma, D; Majumdar, B; Sarma, TK. The CAS is 151-10-0. Through research, I have a further understanding and discovery of 1,3-Dimethoxybenzene

The development of carbonaceous materials as metal-free catalysts integrating different types of catalysis in a single system represents a significant advance in cascade/tandem organic synthesis. Zero-dimensional carbon dots with tuneable optical properties and easily modifiable surface functionalities can be harnessed as a carbocatalyst for merging photooxidation and acid-catalyzed reactions in one pot. Herein, we explore carbon dots decorated with hydrogen sulfate groups as a photocatalyst for the dehydrogenative cross-coupling of xanthenes with ketones, arenes and 1,3-dicarbonyl compounds that showed high efficiency and selectivity under visible-light irradiation. The sulphated carbon dots demonstrate dual catalytic properties, wherein they induced the rapid photooxidation of xanthenes in the presence of molecular oxygen to form a hydroperoxy intermediate followed by coupling of nucleophiles catalysed by the acidic surface functional groups. The methodology represents an operationally simple pathway for the generation of C-C coupling products in a short reaction time with wide substrate scopes under mild conditions. The catalyst is easily separable and can be reused over multiple cycles with good efficiency.

A range of hitherto unexplored biomass-derived chemicals have been evaluated as new sustainable solvents for a large variety of CO2-based carboxylation reactions. Known biomass-derived solvents (biosolvents) are also included in the study and the results are compared with commonly used solvents for the reactions. Biosolvents can be efficiently applied in a variety of carboxylation reactions, such as Cu-catalyzed carboxylation of organoboranes and organoboronates, metal-catalyzed hydrocarboxylation, borocarboxylation, and other related reactions. For many of these reactions, the use of biosolvents provides comparable or better yields than the commonly used solvents. The best biosolvents identified are the so far unexplored candidates isosorbide dimethyl ether, acetaldehyde diethyl acetal, rose oxide, and eucalyptol, alongside the known biosolvent 2-methyltetrahydrofuran. This strategy was used for the synthesis of the commercial drugs Fenoprofen and Flurbiprofen.

The direct reduction of carboxylic acids to aldehydes is a fundamental transformation in organic synthesis. The combination of an air-stable Ni precatalyst, dimethyl dicarbonate as an activator, and silane reductant effects this reduction for a wide variety of substrates, including pharmaceutically relevant structures, in good yields and with no overreduction to alcohols. Moreover, this methodology is scalable, allows access to deuterated aldehydes, and is also compatible with one-pot utilization of the aldehyde products.

A series of benzophenone derivatives bearing naphthalene moiety were designed, synthesized, characterized by H-1 NMR, C-13 NMR, and HRMS and evaluated for their antiproliferative activity against human breast cancer cell line (MCF-7). Most of the tested derivatives showed good to moderate cytotoxicity against MCF-7 cell line. Among them, compound 4u (IC50 = 1.47 +/- 0.14 mu M) was found to be the most active compound, which is more active than the standard drug cisplatin (IC50 = 15.24 +/- 1.27 mu M). In vitro tubulin polymerization in-hibition assay, EBI competition assay, cell cycle analysis, and cell apoptosis assay identified that compound 4u was a new tubulin polymerization inhibitor by targeting the colchicine binding site. Besides, molecular docking study showed that compound 4u has high binding affinities with the colchicine binding site of tubulin through hydrogen bond, cation-pi, and hydrophobic interaction.

An electrosynthesis method for amide bond formation has been developed in an attempt to increase the atom economy for this class of reactions. This anion pool method electrochemically generates strong nucleophiles from amine substrates. The amine nucleophiles then react with acid anhydrides to generate amides, and the by- product from this reaction undergoes further chemical transformations to generate pharmaceutically relevant benzoic esters. These one- pot reactions are operationally simple, are performed at room temperature, and avoid rare transition metals and added bases. The amide synthesis is amenable to primary and secondary amines and a variety of anhydrides with yields up to 90% obtained. Atom economy and process mass index ( PMI) values calculated for this procedure indicate that this process can be considered greener compared to traditional amide synthesis routes used by industry. Furthermore, this electrochemical approach showed unique selectivity when substrates that contained two inequivalent amine moieties were examined.

Because 6-amino-6-deoxy amylose is an important intermediate for many materials, developing a practical pathway to easily prepare it in bulk is of significance. The synthesis of 6-amino-6-deoxy amylose included three reactions. In the chlorination reaction, the crude product could be fully de-esterified under the improved conditions, and the reaction mechanism was re-understood. The azido group was reduced with sodium borohydride in which the reaction conditions were studied in detail. With the improved synthetic pathway, 6-amino-6-deoxy amylose could be easily prepared. The 6-amino-6-deoxy amylose was characterized via its benzamide derivative with(1)H NMR,H-1-C-13 HSQC NMR, and(1)H-H-1 COSY NMR, confirming the hydroxyl group at C(6)of amylose was converted to amino group with a degree of substitution of 98.2%. Additionally, the 6-amino-6-deoxy amylose was analyzed toward iodine reagent and X-ray diffraction, and the corresponding results showed that it was different from amylose in suprastructure and crystal structure.

The novel coronavirus disease COVID-19 that emerged in 2019 is caused by the virus SARS CoV-2 and named for its close genetic similarity to SARS CoV-1 that caused severe acute respiratory syndrome (SARS) in 2002. Both SARS coronavirus genomes encode two overlapping large polyproteins, which are cleaved at specific sites by a 3C-like cysteine protease (3CL(pro)) in a post-translational processing step that is critical for coronavirus replication. The 3CL(pro) sequences for CoV-1 and CoV-2 viruses are 100% identical in the catalytic domain that carries out protein cleavage. A research effort that focused on the discovery of reversible and irreversible ketone-based inhibitors of SARS CoV-1 3CL(pro) employing ligand-protease structures solved by X-ray crystallography led to the identification of 3 and 4. Preclinical experiments reveal 4 (PF-00835231) as a potent inhibitor of CoV-2 3CL(pro) with suitable pharmaceutical properties to warrant further development as an intravenous treatment for COVID-19.
