Unnatural alpha-amino acids are invaluable building blocks in synthetic organic chemistry and could upgrade the function of peptides. We developed a new mode for catalytic activation of amino acid Schiff bases, serving as a platform for highly congested unnatural alpha-amino acid synthesis. The redox active copper catalyst enabled efficient cross-coupling to construct contiguous tetrasubstituted carbon centers. The broad functional group compatibility highlights the mildness of the present catalysis. Notably, we achieved successive beta-functionalization and oxidation of amino acid Schiff bases to afford dehydroalanine derivatives bearing tetrasubstituted carbon. A three-component cross-coupling reaction of an amino acid Schiff base, alkyl bromides, and styrene derivatives demonstrated the high utility of the present method. The diastereoselective reaction was also achieved using menthol derivatives as a chiral auxiliary, delivering enantiomerically enriched alpha-amino acid bearing alpha,beta-continuous tetrasubstituted carbon. The synthesized highly congested unnatural alpha-amino acid could be derivatized and incorporated into peptide synthesis.

Functionalized beta-lactams are highly important motifs in synthetic chemistry. We report an efficient and novel approach to the synthesis of beta-lactams via a copper(i)-catalyzed cascade process involving C(benzyl)-H radical abstraction, intermolecular alkene addition, and intramolecular amination reaction. Variously substituted alkenes were synthesized from vinylacetic acid, leading to the corresponding beta-lactams in moderate to good yields. Preliminary studies indicate that the reaction undergoes a free radical mechanism via a Cu(i)/Cu(ii)/Cu(iii) catalytic cycle.

An article Aging of microplastics affects their surface properties, thermal decomposition, additives leaching and interactions in simulated fluids WOS:000517760200002 published article about ENVIRONMENTAL-SAMPLES; DENSITY POLYETHYLENE; HUMAN HEALTH; TOXICITY; PIGMENTS; BEHAVIOR; IDENTIFICATION; COMPOSITES; ORGANISMS; PYROLYSIS in [Luo, Hongwei; Zhao, Yaoyao; Li, Yu; Xiang, Yahui; He, Dongqin; Pan, Xiangliang] Zhejiang Univ Technol, Coll Environm, Key Lab Microbial Technol Ind Pollut Control Zhej, Hangzhou 310014, Peoples R China in 2020.0, Cited 69.0.

Most microplastics (MPs) have undergone extensive aging in the environment. Aged MPs exhibit different physical and chemical properties from unaged ones. Here, we studied the effects of accelerated aging on the characteristics and pyrolysis of commercial pigmented MPs, as well as pigments leaching and their interactions in simulated gastric and intestinal fluids of mammals. We report that the carbonyl index, surface area, and color change of MPs increased after aging treatment. Cracks and fragmentation of MPs facilitated the accessibility of light and oxygen to internal layer and therefore accelerated the aging process. TGA/GC-MS analysis showed that the high temperature resistance of MN decreased after aging. Thermal decomposition of pigments and polyethylene occurred in temperature ranges of 340-406 degrees C and 406-550 degrees C, respectively. Mono (di)-alkenes and saturated alkanes were the thermal decomposition products of polyethylene. Aging of MPs also caused an increased release of pigments and prolonged aging time led to more release in simulated fluids. Pigments would result in fluorescence quenching of the enzymes through binding interactions once they were released from MPs into simulated fluids. Charge neutralization and polymer bridging accounted for the formation of pigment-enzyme complexes and flocs. These novel findings will allow us to better assess how aging process affects the characteristics, leaching, and toxicity of MPs. (C) 2020 Published by Elsevier B.V.

Simple expressions are presented to determine if a binary system will exhibit a minimum or maximum boiling azeotrope using conventional free energy calculations using molecular simulation or electronic structure calculations in a continuum solvent. The expressions compare the solvation free energy of each component at infinite dilution relative to itself, requiring four total solvation free energy calculations per binary system. The solvation free energies can be related to intermolecular interactions and, therefore, shed insight into why an azeotrope occurs. The application of the expressions is demonstrated for 2366 binary systems using solvation free energies computed using electronic structure calculations in the SM12, SM8, and SMD universal solvent models. The overall success rate for predicting the correct phase behavior was 0.718, 0.711, and 0.685 for SM12, SM8, and SMD, respectively.

I found the field of Environmental Sciences & Ecology very interesting.

Heavy metal pollution in lakes is becoming increasingly of interest to researchers. Because heavy metals have high mobility and do not degrade, they migrate easily between different environmental mediums through processes such as suspended solids deposition, sediment resuspension, and diffusion, among others. These processes are particularly pronounced in shallow lakes since the hydrodynamism is higher in bodies of water with minimal depth. Lake Ulansuhai a typical shallow lake in the Hetao irrigation district in Inner Mongolia-also experiences intense sandstorm activity, which compounds the suspended solids exchange intensity between water and sediment, strengthening the migration of heavy metals in the lake system. This study examines the fate and transport of two heavy metals-Zn and Pb-within this lake, using a field experiment to determine the flux of sediment re-suspension and deposition and a laboratory experiment to modify the QWASI model for shallow bodies of water. The aguivalence and mass balance approaches were used to develop this modified QWASI model. The margins of error between the modeled and the measured average concentrations of Zn and Pb in water were 5.0%-30.6% and 5.8%-29.5%, respectively, and in sediment were 0.3%-4.9% and 0.9-5.5%, respectively. These results suggest that the modified QWASI model developed here could indeed be used to more accurately represent the fate and transport of Zn and Pb during the icefree period of a shallow lake.

Photoredox catalysis is a rapidly evolving platform for synthetic methods development. The prominent use of acridinium salts as a sustainable option for photoredox catalysts has driven the development of more robust and synthetically useful versions based on this scaffold. However, more complicated syntheses, increased cost, and limited commercial availability have hindered the adoption of these catalysts by the greater synthetic community. By utilizing the direct conversion of a xanthylium salt into the corresponding acridinium as the key transformation, we present an efficient and scalable preparation of the most synthetically useful acridinium reported to date. This divergent strategy also enabled the preparation of a suite of novel acridinium dyes, allowing for a systematic investigation of substitution effects on their photophysical properties.
