Final Thoughts on Chemistry for C27H31ClN2O6S

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 190786-44-8, in my other articles.

This work aims to achieve the co-immobilization of laccase and 2,2-binamine di 3 ethylbenzothiazolin-6-sulfonic acid (ABTS) to improve removal capability of the biocatalyst for pollutants while avoiding potential pollution caused by ABTS. The laccase was immobilized on magnetic chitosan nanoparticles modified with amino-functionalized ionic liquid containing ABTS (MACS -NIL) based on Cu ion chelation (MACS -NIL-Cu-lac). The carrier was characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, x-ray diffraction and etc., and electron paramagnetic resonance confirmed the mediator molecule ABTS on the carrier could also play the role of electron transmission. MACS -NIL-Cu-lac presented relatively high immobilization capacity, enhanced activity (1.7-fold that of free laccase), improved pH and temperature adaptability, and increased thermal and storage stability. The removal performance assay found that MACS -NIL-Cu-lac had a good removal efficiency with 100.0 % for 2,4-dichlorophenol in water at 25 degrees C, even when the concentration reached 50 mg/L. Reusability study showed that after six catalytic runs, the removal efficiency of 2,4-dichlorophenol by MACS-NIL-Cu-lac could still reach 93.20/0. Additionally, MACS -NIL-Cu-lac exhibited higher catalytic efficiencies with 100.0 %, 70.5 % and 93.3 % for bisphenol A, indole, and anthracene, respectively. The high catalytic performance in pure water system obtained by the novel biocatalyst co-immobilizing laccase and electron mediator ABTS showed greater practical application value.

Propargylamine (secondary) has been explored as a building block in synthesizing indoles via an ultrasound assisted Pd/Cu-catalyzed coupling-cyclization method. Indoles containing a pyrazole moiety at C-2 attached via the -CH2NH- linker (designed as potential anti-tubercular agents) were synthesized first and then generality/scope of the methodology was expanded by synthesizing other indoles. Unexpected formation of imine side products in first cases helped in synthesizing related (pyrazole)imines via a Cu catalyzed ultrasound assisted aerobic oxidation of precursor amines.

Synthesis of 2,3-disubstituted indoles via a tandem reaction

A strategy for the synthesis of 2,3-disubstituted indoles from 2-allyl-2-(2-nitrophenyl)cyclohexane-1,3-dione has been developed. A wide array of 2,3-disubstituted indoles were accessed in modest to good yieldsviaa tandem reduction/condensation/fragmentation/cyclization sequence. The utility of this strategy was exemplified in the formal syntheses of leucomidine A and goniomitine. The mechanism was confirmed by experiments and density functional theory (DFT) calculations. Differential fragmentation made the reaction more complicated.

Prenylated indole alkaloids and chromone derivatives from the fungus Penicillium sp SCSI0041218

Four new prenylated indole alkaloids (1-4), and four new chromone derivatives (7-10), together with six known compounds (5, 6, and 11-14), have been isolated from the mangrove sediment derived fungus Penicillium sp. SCSI0041218, cultured in the 1% NaCI PDB substrate. The structures of new compounds were determined by analysis of the NMR and MS spectroscopic data. The absolute configuration of the prenylated indole alkaloids were elucidated based on the comparison of ECDs with known analogues. The absolute configurations of the chromone derivatives were determined by time-dependent density functional theory calculations of the ECD spectra. In all of these isolated compounds, penixanthones A and B (12 and 13) exhibited antiallergic activities in vitro. (C) 2017 Elsevier Ltd. All rights reserved.
