Axially Chiral Cyclic Phosphoric Acid Enabled Enantioselective Sequential Additions

Efficient axially chiral cyclic phosphoric acid catalyzed enantioselective sequential additions of 2-aryl-3H-indol-3-ones, aldehydes, and diethyl 2-aminomalonate have been developed, and a new type of nitrogen-containing heterocyclic compounds, 2,3-dihydro-1H-imidazo[1,5-c]indol-9(9aH)-one derivatives, were prepared in good yields and excellent ee values with a wide functional group tolerance, in which the reactivity and enantioselectivity of the substrates were enabled by our newly developed axially chiral cyclic phosphoric acid, (R)-CYC-9-CPA. Furthermore, the corresponding 1H-imidazo[1,5-a]indol-9(9aH)-ones were constructed through the easy oxidation of 2,3-dihydro-1H-imidazo[1,5-a]indol-9(9aH)-one derivatives.

Improved Access to Chiral Tetranaphthoazepinium-Based Organocatalysts Using Aqueous Ammonia as Nitrogen Source

The class of 3,3 ‘-diaryl substituted tetranaphthobisazepinium bromides has found wide application as highly efficient C-2-symmetrical phase-transfer catalysts (PTCs, Maruoka type catalysts). Unfortunately, the synthesis requires a large number of steps and hampers the build-up of catalyst libraries which are often desired for screening experiments. Here, we present a more economic strategy using dinaphthoazepine 7 as the common key intermediate. Only at this stage various aryl substituents are introduced, and only two individual steps are required to access target structures. This protocol was applied to synthesize ten tetranaphthobisazepinium compounds 1a-1j. Their efficiency as PTCs was tested in the asymmetric substitution of tert-butyl 2-((diphenylmethylene)amino)acetate. Enantioselectivities up to 92% have been observed with new catalysts.

Incorporation of a chiral gem-disubstituted nitrogen heterocycle yields an oxazolidinone antibiotic with reduced mitochondrial toxicity

gem-Disubstituted N-heterocycles are rarely found in drugs, despite their potential to improve the drug-like properties of small molecule pharmaceuticals. Linezolid, a morpholine heterocycle-containing oxazolidinone antibiotic, exhibits significant side effects associated with human mitochondrial protein synthesis inhibition. We synthesized a gem-disubstituted linezolid analogue that when compared to linezolid, maintains comparable (albeit slightly diminished) activity against bacteria, comparable in vitro physicochemical properties, and a decrease in undesired mitochondrial protein synthesis (MPS) inhibition. This research contributes to the structure-activity-relationship data surrounding oxazolidinone MPS inhibition, and may inspire investigations into the utility of gem-disubstituted N-heterocycles in medicinal chemistry.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2344-80-1. COA of Formula: C4H11ClSi.

Synthesis and spectral characterization of 1,2-bis(5-methyl/chloro-1H-benzimidazol-2-yl)ethanols and their Co(II), Pd(II) and Zn(II) complexes

1,2-Bis(5-methyl/chloro-1H-benzimidazol-2-yl)ethanols (1 and 2), asymmetric bis-benzimidazoles, and their complexes with CoCl2, PdCl2 and ZnCl2 were synthesized and characterized by elemental analysis, molar conductivity, magnetic moment, TGA, FT-IR (mid-and far-IR), FT-Raman, H-1-and C-13-NMR spectroscopy, ESI-MS and fluorescence spectroscopy. The spectral data suggest that the chiral chelating ligands acted as tridentate through both the C=N nitrogen and OH oxygen atoms. According to the molar conductance, the Zn(II) complexes are non-electrolyte whereas the Co(II) complexes are 1:2 and the Pd(II) complexes are 1:1 electrolytes. The ligands and most of the complexes show triple fluorescence in ethanol. In addition, the Zn(II) complex of 1 (1c)shows significant fluorescence characteristics compared to the other complexes.

Regioselective Deuteration of a 3,4-Dialkoxypyrroline N-Oxide and Synthesis of 8a-d-Indolizidines

A simple and efficient method for C-2 deuterium labeling of 3,4-di-tert-butoxypyrroline N-oxide, a useful chiral building block in azaheterocycles syntheses, is presented. Selective and quantitative deuterium incorporation (> 99 %) was achieved by base-catalyzed H/D exchange in D2O under mild reaction conditions. A mechanistic pathway based on kinetic and computational data was proposed. The labeled nitrone was used in the synthesis of C-8a deuterated (1R,2R,8aR)-lentiginosine.

Effects of residual S-metolachlor in soil on the phyllosphere microbial communities of wheat (Triticum aestivum L.)

S-metolachlor (S-ME) is a widely used chiral herbicide that can cause potential ecological risks via long-term usage. In this work, we chose a model plant, wheat, as the test material to determine the effects of applying 10 mg/kg S-ME to soil on its fresh weight, chlorophyll and malondialdehyde (MDA) content, and superoxide dismutase (SOD) activity and the diversity and structural composition of the phyllosphere microorganisms after 7 and 14 days of exposure. Our work showed that this concentration of residual S-ME in soil only slightly decreased plant biomass and had little effect on lipid peroxida don, the antioxidant enzyme system and chlorophyll content. Interestingly, although the test concentration of S-ME did not exert strong inhibitory effects on the physiological activities of wheat, it decreased the diversity of phyllosphere microbial communities and changed their structure, indicating that microorganisms were more sensitive stress indicators. S-ME reduced the colonization by some beneficial bacteria related to plant nitrogen fixation among the phyllosphere microorganisms, which influenced the growth and yield of wheat because these bacteria contribute to plant fitness. In addition, S-ME affected the association between the host and the composition of the phyllosphere microbial communities under different growth conditions. Our work provides insights into the ecological implications of the effects of herbicides on the phyllosphere microbiome. (C) 2020 Elsevier B.V. All rights reserved.

Nitrogen doped chiral carbonaceous nanotube for ultrasensitive DNA direct electrochemistry, DNA hybridization and damage study

In the interest of developing novel electrocatalyst for high performance DNA biosensing, with distinctive chiral double helix nanostructure, nitrogen doped chiral carbonaceous nanotube (Chiral-CNT) was employed for ultrasensitive label-free DNA biosensing research. Chiral-CNT can quantitative detection of four DNA bases with high sensitivity and selectivity. Without any prehydrolysis and labeling process, direct electrochemistry of single-stranded DNA and double-stranded DNA, qualitative and quantitative detection of DNA hybridization (low detection limit: 0.0268 g L-1) were realized. Moreover, sensitive detection of DNA damage induced by fenton reagent was also realized with low detection limit of 0.0350 mg mL(-1) and high sensitivity of 7.42 mu A mg(-1) mL. The high biosensing performance attributes to the unique chiral structure of Chiral-CNT, leads to efficient interreaction between Chiral-CNT and DNA molecule. (C) 2018 Elsevier B.V.

Accelerated Organic Photoreactions in Flow Microreactors under Gas-Liquid Slug Flow Conditions Using N-2 Gas as an Unreactive Substance

In this work, the [2+2] photocycloaddition of carbonyl compounds with olefins, the Paterno-Biichi-type photoreaction, was performed in a flow microreactor under slug flow (two-phase flow) conditions which are constructed by alternatively introducing nitrogen gas as an unreactive substance into the organic reaction phase. The use of N-2 gas-liquid slug flow conditions permitted the organic photoreactions to proceed more efficiently compared to one-phase flow conditions. A detailed investigation of the influence of the flow mode, the viscosity of the solvents, and the segment length (length of each phase) on the efficiency of the photoreaction was conducted. Based on the results, we concluded that these three factors contribute to the improvement in photoreaction efficiency under slug flow conditions using N-2 gas as an unreactive substance. Further- more, the use of N-2 gas as an unreactive substance was found to be applicable to other Paterno-Biichi-type photoreactions.
