A reagent-controlled chemoselective process has been devised for the synthesis of 4H-1,3-benzoxazines and related biol. important heterocycles in high yields under mild conditions. These scaffolds could be efficiently constructed using two different chemoselective reactions that rely on the choice of reagents and reaction conditions. The treatment of various 2-amino-arylalkyl alcs. with isothiocyanates afforded thiourea intermediates, which were reacted in situ with mol. iodine in the presence of triethylamine to give 2-amino-4H-1,3-benzoxazines, whereas the corresponding 2-amino-4H-1,3-benzothiazines were obtained by the reaction of thiourea intermediates in the presence of T3P (a mild cyclodehydrating agent) and triethylamine as the base. The described protocol represents the first example for the synthesis of 4H-1,3-benzoxazines via the dehydrosulfurization method using mol. iodine as the reagent.

Gholinejad, Mohammad; Dasvarz, Neda; Shojafar, Mohammad; Sansano, Jose M. published the artcile< Starch functionalized creatine for stabilization of gold nanoparticles: Efficient heterogeneous catalyst for the reduction of nitroarenes>, Quality Control of 5344-90-1, the main research area is starch creatine stabilization gold nanoparticle catalyst reduction nitroarene.

Selective reduction of nitroarom. pollutants into amines with recoverable and reusable heterogeneous catalysts is highly desirable. Herein, we prepared and characterized an efficient novel catalyst comprising 4 nm size Au nanoparticles supported on creatine modified starch. Using this catalyst, efficient reduction of nitroarenes into amines at room temperature in aqueous media was achieved. The presence of creatine in the structure of the catalyst plays important role in amount of Au loading, efficiency of the catalyst, recycling times, and leaching of Au compared to starch supported Au without creatine.

An anionic iridium complex [Cp*Ir(2,2′-bpyO)(OH)][Na] was found to be a general and highly efficient catalyst for transfer hydrogenation of ketones and imines with methanol under base-free conditions. Readily reducible or labile substituents, such as nitro, cyano, and ester groups, were tolerated under present reaction conditions.

Maji, Milan; Kundu, Sabuj published the artcile< Cooperative ruthenium complex catalyzed multicomponent synthesis of pyrimidines>, Computed Properties of 403-41-8, the main research area is ruthenium complex catalyst multicomponent preparation pyrimidine.

A new set of 2-(2-benzimidazolyl) pyridine ligand based air and moisture stable ruthenium complexes were synthesized and characterized. The catalytic behaviors of these complexes were evaluated towards the multicomponent synthesis of highly substituted pyrimidines directly from various amidines, primary alcs., and secondary alcs. Among all the metal complexes, 2-hydroxypyridine and benzimidazole fragments containing complex I showed the best reactivity in this reaction. In addition, the N-H proton of benzimidazole and the hydroxyl group of pyridine played a critical role in enhancing catalytic activity. Several control experiments and mechanistic studies were carried out to understand this multicomponent synthesis of pyrimidines using complex I.

G.; Larsen, Scott D. published the artcile< Utilizing a structure-based docking approach to develop potent G protein-coupled receptor kinase (GRK) 2 and 5 inhibitors>, Safety of (1-(Aminomethyl)cyclopropyl)methanol, the main research area is GPCR kinase inhibitor preparation structure; Crystallography; Docking; GPCRs; GRKs; Kinases.

G protein-coupled receptor (GPCR) kinases (GRKs) regulate the desensitization and internalization of GPCRs. Two of these, GRK2 and GRK5, are upregulated in heart failure and are promising targets for heart failure treatment. Although there have been several reports of potent and selective inhibitors of GRK2 there are few for GRK5. Herein, we describe a ligand docking approach utilizing the crystal structures of the GRK2-Gβγ·GSK180736A and GRK5·CCG215022 complexes to search for amide substituents predicted to confer GRK2 and/or GRK5 potency and selectivity. From this campaign, we successfully generated two new potent GRK5 inhibitors, although neither exhibited selectivity over GRK2.

Zijuan tea is a representative anthocyanin-rich tea cultivar in China. In this study, Zijuan tea was used to produce a novel kombucha beverage (ZTK). The physicochem., sensory properties, and antioxidant activity of ZTK were compared with that of black tea kombucha (BTK) and green tea kombucha (GTK). Results indicated that after fermentation, the color of ZTK changed from yellowish-brown to salmon-pink, because its anthocyanins (4.5 mg/L) appeared red in acidic conditions. Meanwhile no significant changes of color were observed in BTK and GTK. The dynamic changes of pH, biomass, and concentrations of sugars, amino acids, and main organic acids were similar in three kombucha beverages, except catechins showing different trends. Moreover, ZTK showed the highest overall acceptability score, antioxidant activity, and concentration of volatiles among the three kombucha beverages. Therefore, Zijuan tea is suitable for the preparation of kombucha beverage with attractive color and health benefits.

Jin, Bei; Wang, Jinguo; Xu, Fengxia; Li, Dianfeng; Men, Yong published the artcile< Hierarchical hollow WO3 microspheres with tailored surface oxygen vacancies for boosting photocatalytic selective conversion of biomass-derived alcohols>, Category: alcohols-buliding-blocks, the main research area is ierarchical hollow WO3 microspheres tailored surface oxygen vacancies; photocatalytic selective conversion biomass derived alc.

Selective conversion of biomass-derived alcs. into carbonyl compounds via visible-light photocatalysis is realized over hierarchical hollow WO3 microspheres with tailored surface oxygen vacancies, which presents the remarkably boosted photoactivity in terms of selectivity and activity, intrinsically attributing to the strong synergetic effect of hierarchical spherical cavity and surface oxygen vacancies simultaneously. The hierarchical spherical cavity, substantially constructed by the self-interconnected nanosheets, enhances the light-harvesting ability via multiple light reflections not only in spherical cavity but also among the self-interconnected nanosheets. Surface oxygen vacancies favor the energy band gap narrowing via forming a miniband just below the conduction band and then extend the photoresponse region, further boosting the light-harvesting ability. Importantly, surface oxygen vacancies function as the electron sinks to capture photoelectrons and thus restrict their recombination probability with holes, finally improving the photoelectron-hole separation efficiency. Meanwhile, this photocatalyst presents excellent reusability, showing its promising potential in practical applications. This work sheds light on a new application of hierarchical WO3 microspheres with tailored surface oxygen vacancies and its strong synergetic effect of hierarchical structures and surface oxygen vacancies on photocatalytic performance, delivering new insights for rationally designing highly active photocatalysts applied in future green and sustainable organic transformation reactions.
