Sterically Crowded Trianglimines-Synthesis, Structure, Solid-State Self-Assembly, and Unexpected Chiroptical Properties

The chiral, triangular-shape hexaimine macrocycles (trianglimines), bearing bulky alkynyl or aryl substituents were synthesized and studied by means of experimental and theoretical methods. The macrocyclization reactions are driven by the extraordinary stability of the trianglimine ring and provided products with high yields. Electrostatic repulsion between imine nitrogen atoms and the substituents forced an anti conformation of the aromatic linkers. Although the DFT-optimized structure of 7 is D-3 symmetrical, in the crystal, the macrocycle adopts a bowl-like molecular shape. The macrocycle self-assembles into tail-to-tail dimers by mutual interdigitation of aromatic moieties. In contrast, macrocycle 8 adopts a rigid pillararene-like conformation. The nature of the substituent significantly affects the electronic properties of the linker. As a result, unexpectedly high exciton Cotton effects are observed in the electronic circular dichroism (ECD) spectra. The origin of these effects was subject of an in-depth study.

Dynamic Conformational Behavior in Stable Pentaorganosilicates

Silicates with five organic groups are conformationally dynamic even with two bidentate ligands. Symmetry breaking by incorporating a single nitrogen or phosphorus atom provides insight into their dynamic behavior. N-containing silicates with bidentate 2-phenylpyridine, biphenyl, and a Me (8), Et (9) or Ph (10) ligand were studied comprehensively by NMR spectroscopy and DFT theory to reveal two isoenergetic conformers with a barrier of ca. 10 kcal mol(-1). P-containing silicate 14 with bidentate triphenylphosphane, biphenyl, and Me ligands is subject to multiple Berry pseudorotations, turnstile rotations, and conformational flexibility of the P-center. The stability increased by masking the P-center with a BH3 group (16). DFT and NMR modeling reveal two isoenergetic conformers for 16 with a barrier of ca. 19 kcalmol(-1) for a complex interconversion pathway. This barrier bodes well for the design of configurationally stable chiral-at-metal transition metal catalysts.

Bioselectivity Induced by Chirality of New Terpenyl Organoselenium Compounds

A series of new chiral benzisoselenazol-3(2H)-ones substituted on the nitrogen atom with three monoterpene moieties-p-menthane, pinane and carane-was synthesized. The compounds were obtained by the reaction of 2-(chloroseleno)benzoyl chloride with an appropriate terpene amine, first synthesized by a multistep methodology starting from the corresponding alcohol (p-menthane system) or alkene (pinene and carene systems). Compounds were tested as antioxidants and anticancer agents. The N-isopinocampheyl-1,2-benzisoselenazol-3(2H)-one was the best peroxide scavenger and antiproliferative agent on the human promyelocytic leukemia cell line HL-60. The N-menthyl-1,2-benzisoselenazol-3(2H)-one revealed the highest anticancer potential towards breast cancer line MCF-7. The influence of structure and chirality on the bio-activity of the obtained organoselenium compounds was thoroughly evaluated.

Chiral Imidazoline Ligands and Their Applications in Metal-Catalyzed Asymmetric Synthesis(dagger)

As a structural analog of oxazoline, imidazoline (4,5-dihydroimidazole) has received much attention in the rational design of chiral ligands. The additional N-substituent provides broader space for fine-tuning of electronic and steric effects, and it offers a good handle for immobilizing onto solid supports. In the past decades, imidazoline ring has emerged as a powerful candidate for the design of chiral nitrogen-containing ligands, as well as a significant alternative for oxazoline ring. Various chiral imidazoline ligands have been designed and utilized in asymmetric organic reactions. These new catalysts can not only be applied in classical reactions, but also be employed to develop new organic reactions with high enantioselectivities. This review provides an overview of chiral imidazoline ligands. Their applications in asymmetric synthesis are also summarized.

Nitrene Transfer Reactions for Asymmetric C-H Amination: Recent Development

C-H bonds are ubiquitous and abundant in organic molecules. If C-H bonds could be directly converted to desired functional groups in a chemo-, site-, and stereoselective manner, C-H functionalization would be a strong and useful tool for organic synthesis. Recent developments in catalytic and enzymatic chemistry have achieved highly sustainable and selective nitrene C-H insertion. Initially, C-H amination was inspired by model studies on enzymatic oxidation and used iminoiodinanes, nitrogen analogs of iodosobenzene, as nitrene precursors. Transition-metal/iminoiodinane systems are well studied and established. These systems can directly introduce sulfonamide groups with excellent stereoselectivity, albeit with co-production of iodobenzene as waste material. Fortunately, the atom economics of this methodology were improved by introducing highly sustainable nitrene sources such as azide compounds and 1,2,4-dioxazol-5-one derivatives. In this review, we present the details of these developments with respect to their catalysts and nitrene sources.

Diquats with Robust Chirality: Facile Resolution, Synthesis of Chiral Dyes, and Application as Selectors in Chiral Analysis

Diquats with extremely high racemization barriers with G(theor) of 233kJmol(-1) at 180 degrees C are described. Reported configurational robustness is due to a combination of two structural features: the rigid o-xylylene tether connecting the nitrogen atoms and the presence of two substituents in the bay region of the bipyridinium scaffold. The straightforward synthesis of diquats, plus facile resolution and derivatization make them attractive for chiral application studies. This is demonstrated by: 1)synthesis of the first non-racemic diquat dyes with pronounced chiroptical properties, and 2)capability of diquats to interact stereospecifically with chiral molecules. This suggests potential for diquat derivatives to be used as chiral selectors in separation methods.

Enlarged Pore Size Chiral Mesoporous Silica Nanoparticles Loaded Poorly Water-Soluble Drug Perform Superior Delivery Effect

Large mesopores of chiral silica nanoparticles applied as drug carrier are worth studying. In this study, chiral mesoporous silica nanoparticles (CMSN) and enlarged chiral mesoporous silica nanoparticles (E-CMSN) with a particle size from 200 to 300 nm were synthesized. Fourier transform infrared spectrometer (FTIR), circular dichroism spectrum, scanning electron microscopy (SEM), transmission electron microscope (TEM), and nitrogen adsorption/desorption measurement were adopted to explore their characteristics. The results showed that the surface area, pore volume, and pore diameter of E-CMSN were higher than those of CMSN due to enlarged mesopores. Poorly water-soluble drug nimesulide (NMS) was taken as the model drug and loaded into carriers using adsorption method. After NMS was loaded into CMSN and E-CMSN, most crystalline NMS converted to amorphous phase and E-CMSN was superior. The anti-inflammatory pharmacodynamics and in vivo pharmacokinetics results were consistent with the wetting property and in vitro drug dissolution results, verifying that NMS/E-CMSN exhibited superior NMS delivery system based on its higher oral relative bioavailability and anti-inflammatory effect because its enlarge mesopores contributed to load and release more amorphous NMS. The minor variations in the synthesis process contributed to optimize the chiral nano-silica drug delivery system.

A chiroptical nanoprobe for highly selective recognition of histidine enantiomers in aqueous media

Histidine is one of the essential amino acids in the human body, and the variation of its concentration in vivo has shown it to align with some liver and kidney diseases. In this work, a series of novel poly(2-oxazoline) derivatives bearing chiral pyrrolidine-triazole moieties in the side chain were designed and synthesized to serve as chemical sensors for histidine. The results demonstrated that the homopolymer HPOx2 is capable of selectively binding optically active histidine through nitrogen/Cu2+ coordination to form complexes exhibiting induced circular dichroism (ICD) signals with signs related to the absolute configuration of the guest compound. Interestingly, the micelle-type nanoparticles assembled from the corresponding amphiphilic copolymer (CPOx2) gave a much stronger CD response, with an intensity five times that of its small molecule- or homopolymer counterparts. The proposed method, based on the chiroptical probe, allows for enantioselective detection of histidine in aqueous media, showing potential application in the field of biomedical assay and chiral drug synthesis.
