Enantioselective friedel-crafts alkylation of N-methylindoles with nitroalkenes catalyzed by chiral bifunctional abietic-acid-derived thiourea-ZnII complexes

The catalytic asymmetric Friedel-Crafts alkylation of N-methylindoles with nitroalkenes catalyzed by bifunctional abietic-acid-derived thiourea-Zn II complexes was investigated. Various types of the nitroalkylated indoles were synthesized under mild conditions and obtained with excellent yields (up to 99 %) and good enantioselectivities (up to 86 % ee). These chiral thiourea catalysts are easily available from the commercial abietic acid.

In situ synthesis and dielectric properties of copper(II) and nickel(II) chiral Schiff base complexes

Two chiral Schiff base-containing complexes, [Cu(L1)](ClO4)2¡¤H2O (1, L1 = (S,S)-N1,N2-bis((1H-imidazol-4-yl)methylene)cyclohexane-1,2-diamine) and [Ni(L2)2](ClO4)2 (2, L2 = (S,S)-N1-((1H-imidazol-4-yl)methylene)cyclohexane-1,2-diamine) were synthesized from the reaction mixture of 1H-imidazole-4-carbaldehyde, (S,S)-1,2-diaminocyclohexane and Cu(ClO4)2¡¤6H2O or Ni(ClO4)2¡¤6H2O in methanol. Single-crystal X-ray diffraction analyses reveal that the in situ generated chiral Schiff base ligands L1 and L2 are bisubstituted and monosubstituted, respectively, corresponding to the different metal ions CuII and NiII. Variable-frequency and -temperature dielectric properties of 1 and 2 have been studied.

Molecular origin for helical winding of fibrils formed by perfluorinated gelators

A chiral low-molecular weight gelator, N,N?-diperfluoroheptanoyl-1, 2(R,R)- or -1,2(S,S)-diaminocyclohexane, was prepared to form a gel of acetonitrile. The conformation of the gelator in fibrils was determined by vibrational circular dichroism spectra, providing a molecular model for self-assembly in a helical fibril.

The antimicrobial properties of some copper(ii) and platinum(ii) 1,10-phenanthroline complexes

Copper(ii) (1Cu-21Cu) and previously established experimental anticancer platinum(ii) metallointercalator complexes (1 Pt-16Pt) have been prepared and investigated for their antimicrobial properties. These complexes are of the general structure [M(I L)(AL)]2+ where IL represents functionalised 1,10-phenanthrolines (1IL-10IL), and A L represents 1,2-diaminoethane, 1S,2S- or 1R,2R-diaminocyclohexane. The structures of synthesised complexes were confirmed using a combination of elemental analysis, UV spectrometry, circular dichroism, 1H and [1H-195Pt]-HMQC NMR, X-ray crystallography, and electrospray ionisation mass spectrometry and where appropriate. Crystallisation attempts yielded single crystals of [Cu(4-methyl-1,10-phenanthroline)(1R,2R- diaminocyclohexane)](ClO4)2 (4Cu), [Cu(5,6-dimethyl-1,10-phenanthroline)(1R,2R-diaminocyclohexane)(H 2O)](ClO4)2¡¤1.5H2O (10 Cu) and [Cu(5,6-dimethyl-1,10-phenanthroline)3](ClO 4)2¡¤5,6-dimethyl-1,10-phenanthroline¡¤2H 2O (21Cu). Growth inhibition of liquid cultures of bacteria (Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa), and yeast (Saccharomyces cerevisiae) discerned the most antimicrobially potent metal complexes ?20 muM, as well as that of their intercalating ligands alone. To further investigate their mode of antimicrobial activity, membrane permeabilisation caused by selected complexes was visualised by means of a cell viability kit under fluorescence microscopy.

Discovery of disubstituted cyclohexanes as a new class of CC chemokine receptor 2 antagonists

We describe the design, synthesis, and evaluation of novel disubstituted cyclohexanes as potent CCR2 antagonists. Exploratory SAR studies led to the cis-disubstituted derivative 22, which displayed excellent binding affinity for CCR2 (binding IC50 = 5.1 nM) and potent functional antagonism (calcium flux IC50 = 18 nM and chemotaxis IC50 = 1 nM). Site-directed mutagenesis studies with 22 suggest the compound is binding near the key receptor residue Glu291, however, 22 is not reliant on Glu291 for its binding affinity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Computed Properties of C6H14N2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 21436-03-3, in my other articles.

Synthesis and Characterization of Heterobenzenacyclo-octaphanes Derived from Cyclotetrabenzoin

We describe the modular synthesis and characterization of several substituted N-hetero benzenacyclooctaphanes (BAOs), a new motif for heteroaromatic conjugated macrocycles. The targets were synthesized via condensation of substituted aromatic ortho-diamines with a cyclic octaketone building block in moderate to excellent yields (41?91 %). We evaluated the optical and electronic properties and the solid-state structures of the targets and discuss their properties through comparison with their linear diphenyl N-heteroacene counterparts.

Induction of supramolecular chirality in di-zinc(ii) bisporphyrin via tweezer formation: Synthesis, structure and rationalization of chirality

Two new supramolecular complexes consisting of an achiral bisporphyrin host and a chiral diamine guest are reported. One shows a remarkably high amplitude bisignate CD signal while the other one shows a very low value. X-ray structure and other spectroscopic investigations of the tweezer complexes clearly rationalize the origin of the optical activity that has so far remained an unresolved issue.

Platinum(II) compounds with enantiomerically pure bis(pinene)-fused bipyridine ligands – Diimine-dichloro complexes and their substitution reactions

The synthesis of chiral square-planar PtII complexes using symmetrical and unsymmetrical bis(pinene)-fused 2,2?-bipyridine is described. The neutral diimine dichloro complexes show a strong deviation of the coordination sphere from planarity if the pinene groups are attached at the 5-and 6-positions of the pyridine rings. However, this distortion does not occur in parallel with the chiral configuration at the diimine ligands. The substitution of the two cis-chloro ligands with diamines to form five-membered chelate rings shows little diastereoselectivity when racemic mixtures of chiral diamines are used. Also, ligands that are prochiral at the ligating centers show little selectivity upon coordination.

Novel chiral Schiff base macrocycles containing azobenzene chromophore: gelation and guest inclusion

A novel chiral Schiff base macrocycle 1 was synthesized by [3+3] condensation of enantiomerically pure trans-1,2-diaminocyclohexane with azobenzene-4,4?-dicarbaldehyde. Subsequent reduction of 1 afforded macrocyclic hexamine 2 having three azobenzene units. The former could be converted into a benzene gel, while the latter could include several aromatic guest molecules.
