A simple and efficient protocol for the formylation of amines with formic acid, catalyzed by a polyoxometalate-based chromium catalyst, is described. Notably, this method shows excellent activity and chemo-selectivity for the formylation of primary amines; diamines have also been successfully employed. Importantly, the chromium catalyst is potentially non-toxic, environmentally benign and safer than the widely used high valence chromium catalysts such as CrO3 and K2Cr2O7. The catalyst can be recycled several times with a negligible impact on activity. Finally, a plausible mechanism is provided based on the observation of intermediate and control experiments.

I found the field of Chemistry very interesting. Saw the article ESIPT-AIE active Schiff base based on 2-(2 ‘-hydroxyphenyl)benzo-thiazole applied as multi-functional fluorescent chemosensors published in 2021.0. Category: amides-buliding-blocks, Reprint Addresses Zheng, XJ (corresponding author), Beijing Normal Univ, Coll Chem, Beijing Key Lab Energy Convers & Storage Mat, Beijing 100875, Peoples R China..

Three AIE (aggregation-induced emission)-ESIPT (excited-state intramolecular proton transfer) active 2-(2-hydroxyphenyl)benzothiazole derivatives, HL1, HL2 and HL3 with one, two and three rotatable phenyl groups, were obtained and characterized. Their AIE properties in THF/HEPES solution were investigated in detail. HL2 shows the best AIE performance with 71-fold fluorescence enhancement, while HL3 only shows a 9-fold enhancement. With the AIE property, HL1 and HL2 could act as fluorescence chemosensors to detect Cu2+ ions via the turn off mode in THF/HEPES media. With the ESIPT property, HL1 and HL2 could also detect Zn2+ ions via the turn on mode in EtOH/HEPES media. During the detection process, both demonstrate rapid response and high contrast before and after the addition of metal ions. The species formed in the detection system were investigated. The results of X-ray single-crystal diffraction confirm that Zn2+ is coordinated with the oxygen atom and Schiff base nitrogen atom instead of the benzothiazole nitrogen atom in the tetrahedron geometry. Moreover, the chemosensors were successfully constructed into handy fluorescence test papers for Cu2+ and Zn2+ detection.

Electroorganic synthesis is an environmentally friendly alternative to traditional synthetic methods; however, the application of this strategy is heavily hindered by low product selectivity. Metal-organic frameworks (MOFs) exhibit high selectivity in numerous catalytic reactions; however, poor conductivity heavily limits the application of MOFs in electroorganic synthesis. To realize the electrocatalytic application of MOFs in selective electroorganic synthesis, a practically applicable strategy by suspending ion electrocatalysts in charged MOFs is herein reported. This approach could markedly improve the product selectivity in electroorganic synthesis. In the electrocatalytic oxidative self-coupling of benzylamine experiments, the imine product selectivity is markedly improved from 61.3 to 94.9 %, when the MOF-based electrocatalyst is used instead of the corresponding homogeneous electrocatalyst under the identical conditions. Therefore, this work opens a new route to improve the product selectivity in electroorganic synthesis.

The hepatitis C virus RNA-dependent RNA polymerase NS5B is responsible for the replication of the viral genome. Previous studies have uncovered NTP-mediated excision mechanisms that may be responsible for aiding in maintaining fidelity (the frequency of incorrect incorporation events relative to correct), but little is known about the fidelity of NS5B. In this study, we used transient-state kinetics to examine the mechanistic basis for polymerase fidelity. We observe a wide range of efficiency for incorporation of various mismatched base pairs and have uncovered a mechanism in which the rate constant for pyrophosphate release is slowed for certain misincorporation events. This results in an increase in fidelity against these specific misincorporations. Furthermore, we discover that some mismatches are highly unfavorable and cannot be observed under the conditions used here. The calculated fidelity of NS5B ranges between 10(-4)-10(-9) for different mismatches.

Insect-microbial symbioses have vast biochemical diversity, which is beneficial to produce bioactive secondary metabolites. In this study, chemical examination of a Streptomyces sp. associated with a mud dauber wasp led to the isolation of fourteen compounds. Their structures were determined by spectroscopic methods and comparison with literature data. Among the isolates, compounds 1,2,3-benzotriazin-4(1H)-one and 4-(2-aminoethyl)phenyl acetate were first reported from this species. Bioactivities of the isolated compounds were assayed for the first time against hexokinase II. 4-(2-Aminoethyl)phenyl acetate, germicidin B, phenylacetic acid, isogermicidin A and germicidin C displayed significant inhibitory activity against hexokinase II, with the IC50 values of 5.11, 7.11, 7.15, 8.45 and 8.78 mu M, respectively.

A simple protocol for the protection of amines was realized through a base-catalyzed one-pot reaction of dimedone, beta-nitroalkene, and amine. Employing this strategy, a variety of amines/amino acids were protected in excellent yields. These acid/base stable protected amines can be deprotected by either ethylene diamine or hydrazine hydrate under mild conditions. The practical application of this orthogonal protecting group was demonstrated by the synthesis of cyclic peptide melanotan II via SPPS.
