The application of quasi-enantiomeric trianglamine macrocycles as chiral probes for anion recognition in ion trap ESI mass spectrometry

This paper reports the synthesis and application of quasi-enantiomeric trianglamine macrocycles for chiral analysis using ion trap ESI mass spectrometry. The quasi-enantiomeric macrocycles were shown to display chiroselection towards a series of enantiomerically pure carboxylic acids and therefore act as chiral probes for anions in the gas phase and in solution.

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.COA of Formula: C6H14N2, you can also check out more blogs about21436-03-3

Facile preparation and dual catalytic activity of copper(i)-metallosalen coordination polymers

Three copper(i)-metallosalen coordination polymers (CPs), {[NiII(SalImCy)]2(CuICN)9}n (1), {[CuII(SalImCy)]2(CuICN)9}n (2) and {[NiII(SalImCy)](CuII)2¡¤DMF}n (3) were prepared by direct combination of NiII/CuII(salen) motifs with [CuICN]n chains and Cu2I2 clusters via the metalloligand strategy. The mixed-valence and mixed-metal CPs could effectively catalyze both the oxidation of aromatic alcohols to ketones and aldehydes under mild conditions and photocatalytic degradation of organic dye methylene blue (MB). This work demonstrates the effective integration of transition metal catalytic NiII/CuII(salen) units and photoactive copper(i) species in a single solid polymer to meet the demand for catalytic materials with the dual catalytic properties.

Enantioselective analysis of an asymmetric reaction using a chiral fluorosensor

(Chemical Equation Presented) An axially chiral 1,8-dipyridylnaphthalene N,N?-dioxide has been employed in enantioselective fluorescence analysis of the enzymatic kinetic resolution of trans-1,2-diaminocyclohexane. The procedure eliminates cumbersome purification and derivatization steps required by traditional methods. The results demonstrate the potential of fluorescence spectroscopy using suitable chiral chemosensors for real-time analysis of the enantiomeric composition of chiral compounds and for high-throughput screening of asymmetric reactions.

Synthesis, self-association and chiroselectivity of isotopically labeled trianglamine macrocycles in the ion trap mass spectrometer

The synthesis and self-association of chiral isotopically labeled trianglamine macrocycles under electrospray mass spectrometer conditions in an ion trap are described. A moderate diastereoselectivity in the self-association process was observed providing a synthetic model system for the investigation of chiral self-association in the gas phase. The first non-covalently bound dimer exclusively bonded through aromatic-aromatic interactions was observed in the gas phase. Evidence for self-association in solution was observed by diffusion nuclear magnetic resonance spectroscopy. Copyright

Design, synthesis, and biological evaluation of pirenzepine analogs bearing a 1,2-cyclohexanediamine and perhydroquinoxaline units in exchange for the piperazine ring as antimuscarinics

Pirenzepine (2) is one of the most selective muscarinic M1 versus M2 receptor antagonists known. A series of 2 analogs, in which the piperazyl moiety was replaced by a cis- and trans-cyclohexane-1,2-diamine (3-6) or a trans- and cis-perhydroquinoxaline rings (7 and 8) were prepared, with the aim to investigate the role of the piperazine ring of 2 in the interaction with the muscarinic receptors. The structural change leading to compounds 3-6 abolished in binding assays the muscarinic M1/M2 selectivity of 2, due to an increased M2 affinity. Rather, compounds 3-6 displayed a reversed selectivity showing more affinity at the muscarinic M2 receptor than at all the other subtypes tested.

Synthesis and some octahedral complexes of a chiral triaza macrocycle

The chiral and bulky tacn (1,4,7-triazacyclononane, L1) analogue chtacn (2,5,8-triazabicyclo[7.4.01,9]tridecane, L2), which has a cyclohexane ring fused to the tacn framework, has been synthesized commencing with (¡À), (+)-or (-)-trans-cyclohexane-1,2-diamine. Syntheses and properties of cobalt(III), nickel(II), chromium(III) and iron(III) complexes are described. In the complex bis(RR-2,5,8-triazabicyclo[7.4.01,9]tridecane)cobalt(III) chloride hexafluorophosphate the cyclohexane rings and pairs of adjacent secondary amines occupy an approximate plane around the cobalt ion, with the remaining secondary amines in each tridentate ligand in trans dispositions. A large positive Cotton effect occurs under the low energy absorption band in the circular dichroism spectrum of this cobalt(III) complex of the R,R-(-)-chtacn ligand. In the dinuclear complex aqua-di-mu-chloro-chlorobis(SS-2,5,8-triazabicyclo[7.4.0 1,9]tridecane)dinickel(II) perchlorate each nickel atom is bound to a tridentate macrocyclic ligand in different dispositions, with the distorted octahedron of each nickel completed by two bridging chloride ions and either a chloride ion or aqua molecule. For [M(Ln)2]n+ complexes, electronic maxima are shifted slightly to lower energy and reduction potentials slightly to more negative potential in the case of L2 compared with L1.

Development of recyclable chiral macrocyclic metal complexes for asymmetric aminolysis of epoxides: Application for the synthesis of an enantiopure oxazolidine ring

New recyclable chiral salen complexes Cr(iii)1-7 were synthesized from various macrocyclic chiral ligands having multistereogenic chiral centers which work synergistically to give the best results in terms of the enantioselectivity and yield of the products. Among the synthesized complexes, the Cr(iii)-4 salen complex efficiently catalyzed the ring opening reaction of various aromatic ester epoxides, trans-epoxides and meso-epoxides with anilines to furnish the corresponding beta-amino-alpha-hydroxyl esters and beta-amino alcohols with an excellent ee of up to 99% and a high yield of up to 95%. Furthermore, the chirally pure beta-amino-alpha-hydroxyl esters were converted into pharmaceutically important oxazolidine ring systems. Moreover, the chromium catalyst was recycled up to 5 cycles with the retention of its activity.

Effect of various parameters and mechanism of reversal order of elution in chiral HPLC

Background: Chiral separation involves many phenomena in which the elution order of the enantiomers has its unique position. The phenomenon of elution order of the enantiomers has also been used in the determination of optical purity which is favorable to elute the major component after minor enantiomeric impurity but the main problem is that, this phenomenon is rare. Results: This review rumors the reversal order of elution of many chiral molecules in HPLC. Besides, this review pronounces the effects of pH, derivatisation of drugs, the composition of the mobile phase, and temperature on the reversal order of elution of chiral drugs. The efforts are also made to discuss the possible future perspectives of reversal order of elution. Conclusion: Various parameters such as pH, mobile phase composition, temperature, and chemical structure of the analytes play a role in the phenomena of the reversal order of elution of many chiral molecules which are discussed in the article.

Design and electropolymerization of new chiral thiophene-salen complexes

New chiral thiophene-containing salen ligands have been synthesized. The corresponding metal complexes (Co, Cu, Cr and Ni) were prepared and electropolymerized at a platinum electrode by cyclic voltammetry. The resulting polymers exhibited stable and quasi-reversible redox processes when submitted to voltammetric repeated scans, whatever the nature of the metal or the structure of the ligand. Preliminary catalytic tests have been performed to examine the efficiency of these new chiral polymeric complexes as asymmetric heterogeneous catalysts.
