Protecting-Group-Directed Diastereoselective Synthesis of Substituted Tetrahydropyrroloquinolines

An efficient and protecting-group-directed highly diastereoselective (>= 99:1) synthesis of tetrahydro-3H-pyrrolo[2,3-c]quinolines bearing four contiguous chiral centers was achieved by using intermolecular Michael addition followed by intramolecular Mannich cyclization strategy. The domino reaction proceeded well with a broad scope of substrates under mild conditions and afforded the corresponding products in good to excellent yields. The synthetic protocol provided a straightforward synthetic route to tetrahydropyrroloquinolines as single diastereomers, which are difficult to synthesize by other methodologies.

Chiral separation of terbutaline and non-steroidal anti-inflammatory drugs by using a new lysine-bridged hemispherodextrin in capillary electrophoresis

A method for the separation of a mixture of terbutaline and non-steroidal anti-inflammatory drugs was developed using capillary electrophoresis with a new hemispherodextrin, ad hoc designed, the lysine – bridged hemispherodextrin (THIXSH). The use of lysine residues to bridge the trehalose capping unit moiety to the cyclodextrin cavity gives rise to a receptor with two long chains with amine nitrogen atoms, whose charge can be easily tuned as a function of the solution pH. The new hemispherodextrin was accurately characterised by ESI-MS and NMR spectroscopy, also highlighting its protonation behaviour. Circular dichroism and ESR spectroscopy measurements were also carried out to test its inclusion ability towards anthraquinone-3-sulfonate and its metal coordination ability towards copper(II) ion, respectively. Analogously to the other hemispherodextrins, the main skill of this new derivative lies in its chiral selector properties, as shown by the separation of the enantiomeric pairs of terbutaline and ibuprofen, flurbiprofen, suprofen and tiaprofenic acid by capillary electrophoresis. The focused use of the solution equilibria involved in the separations made it possible to understand the phenomena occurring in solution, and to finely tune the charge status of the receptor. In this way the chiral separation of the racemic mixture was successfully obtained, even if the receptor was individually used, differently by the other hemispherodextrins previously studied whose chiral separation capabilities are present only if used as binary mixtures.

Buckling analysis of boron nitride nanotube with and without defect using molecular dynamic simulation

In this paper, axial buckling of boron nitride nanotubes (BNNTs) has been investigated. In order to achieve this purpose, the molecular dynamics was adopted and the potential between the atoms of boron and nitrogen was considered as Tersoff type. For scrutinising the influence of chirality on the critical loads, zigzag, armchair and chiral BNNTs were utilised. The buckling of BNNTs was studied based on three types of multiple mono-atomic vacancy defects. The findings of the present study revealed that the impact of length, diameter and defect of BNNTs on critical loads was significant. Further, it was found that with increasing the length of BNNT the critical loads were decreased and also the critical loads were higher in zigzag BNNTs compared with armchair ones.

Insight Into Microbial Applications for the Biodegradation of Pyrethroid Insecticides

Pyrethroids are broad-spectrum insecticides and presence of chiral carbon differentiates among various forms of pyrethroids. Microbial approaches have emerged as a popular solution to counter pyrethroid toxicity to marine life and mammals. Bacterial and fungal strains can effectively degrade pyrethroids into non-toxic compounds. Different strains of bacteria and fungi such as Bacillus spp., Raoultella ornithinolytica, Psudomonas flourescens, Brevibacterium sp., Acinetobactor sp., Aspergillus sp., Candida sp., Trichoderma sp., and Candia spp., are used for the biodegradation of pyrethroids. Hydrolysis of ester bond by enzyme esterase/carboxyl esterase is the initial step in pyrethroid biodegradation. Esterase is found in bacteria, fungi, insect and mammalian liver microsome cells that indicates its hydrolysis ability in living cells. Biodegradation pattern and detected metabolites reveal microbial consumption of pyrethroids as carbon and nitrogen source. In this review, we aim to explore pyrethroid degrading strains, enzymes and metabolites produced by microbial strains. This review paper covers in-depth knowledge of pyrethroids and recommends possible solutions to minimize their environmental toxicity.

Metal-catalyzed aziridination of alkenes by organic azides: a mechanistic DFT investigation

The DFT B3LYP/6-31G(d,p) approach is used to study alkene aziridination by azides through catalyzed routes involving a metal nitrenoid intermediate. The catalysts studied are copper(II) triflate, cobalt(II) porphin, and ruthenium(II) porphin. Three azides RN3 (R = H, Me, and Ac) react with alkene substrates in the presence of these catalysts leading to aziridine formation by a two-step catalyzed mechanism. The azide reacts with the catalyst in Step I to first form a metal nitrenoid via transition state TS1. The Ru(porph) catalyst is particularly effective for Step I. Then, the metal nitrenoid adds to alkene through Step II via TS2 giving the aziridine, the metal catalyst, and N-2. Cu(trfl)(2) is most effective as a catalyst for Step II. The facility order H > Me > Ac (with respect to the azide R group) holds for Step I and the reverse order for Step II. MP2 results on some select minima for Step II largely reproduce the DFT trends. Transition states TS1 and TS2 are characterized as being early or late in good accord with the Hammond postulate.

A Ni(salen)-Based Metal-Organic Framework: Synthesis, Structure, and Catalytic Performance for CO2 Cycloaddition with Epoxides

A three-dimensional (3D) chiral metal-organic framework [Cd-2{Ni(salen)}(DMF)(3)]4 center dot DMF center dot 7H(2)O (1) based on a new enantiopure tetracarboxyl-functionalized metallosalen Ni(H(4)salen) {where H(6)salen is (R,R)-N,N-bis[3-tert-butyl-5-(3,5-dicarboxybenzyl)salicylidene]-1,2-diphenylethylenediame} was synthesized and characterized by infrared spectroscopy, thermogravimetric analysis, nitrogen and carbon dioxide adsorption, and powder and single-crystal X-ray diffractions. In 1, the dinuclear Cd-2 cluster [Cd-2(COO)(4)(DMF)(3)] as a node is cross-linked by four isophthalate groups on the salen ligands, forming a 2D lamellar structure, which are further linked by Ni(salen) into the 3D network with a 1D open channel (ca. 7.0 x 8.0 angstrom(2)) along the a axis. On account of its porosity, Lewis acid sites, and moderate uptake for CO2, 1 can be used as an efficient heterogeneous catalyst for the CO2 cycloaddition with epoxides under relatively mild conditions. Moreover, the bulky epoxide shows a decrease in activity with an increase in the alkyl chain length of the substrate as a result of the confinement effect of 1, showing size-dependent selectivity.

Chiral evolution of carbon dots and the tuning of laccase activity

Chirality has attracted extensive attention in many fields ranging from chemistry to life sciences. Carbon dots (CDs) with good biocompatibility and unique photochemical properties have become a new star in the nanocarbon family. Endowed with chirality, CDs will exhibit more marvellous properties and bridge the fields of material chemistry and life sciences tightly. Herein, we report a facile one-step alkali-assisted electrochemical method to fabricate chiral CDs from cysteine (cys). We showed the chiral evolution of CDs with highly symmetrical circular dichroism (CD) signals in the range from 205 to 350 nm. These chiral CDs have been further demonstrated to be capable of tuning the activity of laccase: the L-CDs can improve the activity of the enzyme up to 20.2%, whereas the D-CDs decrease the activity to 10.4%. A series of experiments confirm that it is the synergistic effect of nanosize and chirality of CDs that induces the change in the structure of laccase and thus leads to the tuning of the laccase activity.

Direct Aerobic Strategy for Synthesis of Imines via Alcohols and Amines Promoted by Ruthenium(II) (eta(6)-p-cymene) Complexes

Neutral ruthenium(II) p-cymene complexes were synthesised by complexation of [Ru(eta(6)-p-cymene)(-Cl)Cl](2) with substituted methyl-2-pyrrolyl ketone benzhydrazone ligands in good yields. The characterization of the synthesised complexes was accomplished by analytical and spectroscopic techniques (FT-IR, UV-Vis, NMR, and ESI-MS). Crystal structures of two of the complexes exhibited that the hydrazone ligand was bonded to ruthenium ion in a bidentate fashion via imine nitrogen and imidolate oxygen and witnessed ruthenium centered pseudo-octahedral geometry. The catalytic feasibility of these Ru(II) complexes was explored for the direct aerobic synthesis of imine from the coupling of alcohols and amines in toluene medium with Cs2CO3 as a base without molecular sieves or any additives. The scope and versatility of the present catalytic system were performed with the diverse range of alcohols and amines such as primary/secondary aromatic, aliphatic, heteroaromatic, cyclic as well as chiral substrates under open atmospheric condition. Further, the tolerance of steric and electronic effects on substrates was evaluated. Besides, the effect of promoters on the reaction including solvents, bases, temperatures and catalyst loading was carried out as well.
