Lin, Yun;Chen, Senlin;Hu, Nanjun;Lai, Yanhua research published 《 Effect of UV irradiation time on quality of low-grade aging tobacco leaves》, the research content is summarized as follows. Objective: This study aims to improve the quality and utilization of low-grade aging tobacco leaves. Methods: Tobacco leaves were irradiated by UV, and the changes of phys. characteristics, sensory quality, starch content, protein content, routine chem. components and aroma components of aging tobacco leaves under different UV irradiation time were comprehensively investigated. Results: The results showed that the quality in all aspects of tobacco leaves treated by UV irradiation for 15 min to 60 min was improved in varying degrees. The improvement effect was obtained for tobacco leaves treated by 30 min of UV irradiation The filling value, sugar-to-nicotine ratio and the total amount of aroma components increased, the contents of starch and protein decreased, and the sensory quality was improved under such UV irradiation scheme. After 75 min of UV irradiation, the processability of tobacco leaves became worse, and the total amount of tobacco aroma decreased gradually, and the flavor style was changed with the extend of time. Conclusion: UV irradiation time in an appropriate range can improve the quality of aging tobacco leaves to a certain extent. However, if the irradiation time is long, some of the phys. and chem. properties will be adversely affected.

In this study, a series of 4-benzoylamino-1H-pyrazole-3-carboxamide derivatives I (R = Ph, pyridin-3-yl, 2-methyl-5-([3-(morpholin-4-yl)propyl]carbamoyl)phenyl, etc.) was designed, synthesized, and evaluated. The most selective compound I (R = 6-carbamoylpyridin-3-yl) in this series exhibited high potency towards CDK2 and had effective anti-proliferative activity against A2058 melanoma cell line and MV4-11 leukemia cell line while exhibiting low toxic effect on human normal cell lines MRC5 and LX2. The mol. modeling illustrated that compound I (R = 6-carbamoylpyridin-3-yl) had the similar binding mode with CDK2 as C-73, the most selective CDK2 inhibitor reported so far, which might account for selectivity against CDK2 over CDK1.

The exptl. and DFT computational studies on the directing ability of chalcogenoether motifs in Pd-catalyzed atroposelective C-H functionalization was presented. The thioether motif was found to be a superior directing group compared to the corresponding ether and selenoether in terms of reactivity and enantiocontrol. Remarkably, DFT calculation provided a predictive model for the optimization of reaction conditions and the interpretation of the origin of enantioselectivity. Both Pd-catalyzed enantioselective C-H olefination and allylation reactions were successfully developed using chiral phosphoric acids as efficient ligands, providing a broad range of axially chiral biaryls in good yields with excellent enantioselectivities. The highly enantio- and diastereoselective construction of polyaryls bearing multiple stereogenic axes, gram-scale reaction and various chem. transformations make this protocol more attractive and significant.

Abstract: Primary alkyl halides have broad utility as fine chems. in organic synthesis. The direct halogenation of alkenes is one of the most efficient approaches for the synthesis of these halides. Internal alkenes, in particular mixtures of isomers from refineries, constitute readily available and inexpensive feedstock and are the most attractive starting materials for this synthesis. However, the hydrohalogenation of alkenes generally affords branched alkyl halides; there are no catalytic methods to prepare linear alkyl halides directly from internal alkenes, let alone from a mixture of alkene isomers. Here a report the remote oxidative halogenation of alkenes under palladium catalysis via which both terminal and internal alkenes yield primary alkyl halides efficiently. Engineering pyridine-oxazoline ligands by introducing a hydroxyl group is essential for achieving excellent chemo- and regioselectivity. The catalytic system is also good for the mixture of alkene isomers generated from dehydrogenation of alkanes, providing a window to investigate the high-value utilization of inexpensive alkanes.
