Chiral oxygen ligands

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Polyhedron called Synthesis and characterization of copper complexes with the 2,3-dicyano-5,6-dimercaptopyrazine ligand: Magnetic properties of a ferrocenium salt, Author is Belo, D.; Figueira, M. J.; Santos, I. C.; Gama, V.; Pereira, L. C.; Henriques, R.

(Bu4N)2[Cu(dcdmp)2], Bu4N[Cu(dcdmp)2] and [FeCp*2]2[Cu(dcdmp)2] (H2dcdmp = 2,3-dicyano-5,6-dimercaptopyrazine; Cp* = decamethylferrocenium) were obtained and characterized. (Bu4N)2Cu(Hdcdmp)2 crystallizes in the triclinic system, space group P1̅, Z = 1, with a 9.9512(6), b 10.541(1), c 13.221(1) Å, α 69.756(9), β 88.112(6) and γ 79.658(7)°. Its crystal structure consists of layers of well isolated square planar Cu(dcdmp)22- anions alternating with layers of Bu4N+ cations along b + c, and the magnetic properties in the range 2-300 K are close to those of an ideal paramagnet with an effective magnetic moment of 1.7 μB/f.u. Bu4N[Cu(dcdmp)2] crystallizes in the monoclinic space group C2/c, Z = 8, with a 35.281(4), b 9.501(1), c 21.885(2) Å and β 109.842(9)°, being isostructural with the Au analog previously described. [Fe(Cp*)2]2[Cu(dcdmp)2] crystallizes in the monoclinic system, space group C2/c, Z = 4, with a 15.891(1), b 10.5133(7), c 30.264(3) Å and β 91.105(2)°. Its crystal structure consists of out-of-registry columns, parallel to b, of alternated dianions and side-by-side pairs of cations, …A2-(D+D+)A2-(D+D+). This compound behaves as a paramagnet with weak antiferromagnetic interactions and no ordering down to 1.7 K. The magnetic properties, due to both cation and anion S = 1/2 contributions, show a large anisotropy, ascribed essentially to the g-factor anisotropy of the Fe(Cp*)2cations.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

We are presenting a new derivative of the fluorubine family which exhibits highly fluorescent activity. 5-Phenyl-dihydro[5,6,7,12,13,14]-hexaazapentacene was synthesized via two subsequent cyclization reactions starting from com. available starting materials. Its properties were studied intensively via UV-vis and fluorescence spectroscopy, as well as cyclic voltammetry and quantum chem. calculations Furthermore, we found a strong pH-sensitivity, which influences the photo- and electrochem. properties heavily. Thereby, it is possible to tune its properties from an electron-rich donor to a highly electron-deficient acceptor material.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, U.S. Gov’t, Non-P.H.S., Brain Research called Effects of some conformationally restricted GABA analogs on GABA membrane binding and nerve ending transport, Author is Hitzemann, Robert J.; Loh, Horace H., which mentions a compound: 3685-23-2, SMILESS is N[C@H]1CC[C@H](CC1)C(O)=O, Molecular C7H13NO2, Electric Literature of C7H13NO2.

By using a series of aminocyclopentane- and aminocyclohexanecarboxylic acids, as well as some naturally occurring amino acids, it was possible to determine some aspects of the spatial topog. of the GABA [56-12-2] membrane binding and transport sites in the rat brain. The Na-independent GABA binding site had a different spatial topog. than the Na-dependent binding site in that (±)-trans-3-aminocyclopentanecarboxylic acid (I) [19297-28-0] was 7-fold more potent than (±)-cis-3-aminocyclopentanecarboxylic acid (II) [49805-32-5] in inhibiting Na-independent binding, but only 1.6 times more potent in inhibiting Na-dependent binding. The nerve ending GABA transport site was similar to the Na-dependent GABA binding site in that it accommodated both I and II. However, the transport site differed from the binding site in that II was a potent inhibitor of transport but a weak inhibitor of binding. In addition to the differences in spatial characteristics, differences in the subcellular distribution of Na-independent and Na-dependent binding sites were observed The former were found primarily in the nerve ending-mitochondrial fraction, whereas the latter were primarily found in the microsomal fraction.

Cis-4-(Acetylamino)-N-(methyl)cyclohexanecarboxamide has been selected as all carbon ring analog of previously described 5-(amino)piperidinone-2-carboxylate systems. The potential β-turn-inducing properties of this model compound are evaluated by means of NMR anal. and mol. modeling. It was found that suitable as β-turn-inducing scaffold. Apparently, the planar lactam function in the native (amino)(oxo)piperidinecarboxylate systems is important to impose a correct conformation for β-turn induction.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-Methyl-1H-pyrrole( cas:616-43-3 ) is researched.SDS of cas: 616-43-3.Muradov, Nazim; Fidalgo, Beatriz; Gujar, Amit C.; T-Raissi, Ali published the article 《Pyrolysis of fast-growing aquatic biomass -Lemna minor (duckweed): Characterization of pyrolysis products》 about this compound( cas:616-43-3 ) in Bioresource Technology. Keywords: pyrolysis aquatic biomass Lemna duckweed oil char gas biofuel. Let’s learn more about this compound (cas:616-43-3).

The aim of this work was to conduct the exptl. study of pyrolysis of fast-growing aquatic biomass -Lemna minor (commonly known as duckweed) with the emphasis on the characterization of main products of pyrolysis. The yields of pyrolysis gas, pyrolytic oil (bio-oil) and char were determined as a function of pyrolysis temperature and the sweep gas (Ar) flow rate. Thermogravimetric/differential thermogravimetric (TG/DTG) analyses of duckweed samples in inert (helium gas) and oxidative (air) atm. revealed differences in the TG/DTG patterns obtained for duckweed and typical plant biomass. The bio-oil samples produced by duckweed pyrolysis at different reaction conditions were analyzed using GC-MS technique. It was found that pyrolysis temperature had minor effect on the bio-oil product slate, but exerted major influence on the relative quantities of the individual pyrolysis products obtained. While, the residence time of the pyrolysis vapors had negligible effect on the yield and composition of the duckweed pyrolysis products.

Phthalocyanines (Pc) and their aza-analogs azaphthalocyanines (AzaPc) (tetrapyrazinoporphyrazines) with eight n-octylsulfanyl or tert-butylsulfanyl peripheral substituents and different central metals (Mg, Zn, metal-free) were synthesized. Dimerization constants Kd and absorption spectra of pure monomeric and dimeric magnesium complexes in toluene were calculated using series of absorbances at different concentrations The bulky tert-butylsulfanyl substituents were found to be much better inhibitors of aggregation than long alkyl chains. Also Pc are less aggregated in organic solvents then AzaPc, short explanation is given. Singlet oxygen production of Pc and AzaPc was compared using dye-sensitized photooxidation of 1,3-diphenylisobenzofuran in pyridine. Both Pc and AzaPc showed similar activity not dependent on type of peripheral substitution. Zinc complexes of both Pc and AzaPc exceeded the magnesium ones and metal-free dyes in singlet oxygen production approx. twice.
