Reductive Amination of Ketonic Compounds Catalyzed by Cp*Ir(III) Complexes Bearing a Picolinamidato Ligand

Cp*Ir complexes bearing a 2-picolinamide moiety serve as effective catalysts for the direct reductive amination of ketonic compounds to give primary amines under transfer hydrogenation conditions using ammonium formate as both the nitrogen and hydrogen source. The clean and operationally simple transformation proceeds with a substrate to catalyst molar ratio (S/C) of up to 20,000 at relatively low temperature and exhibits excellent chemoselectivity toward primary amines.

Increasing the complexity of oxoporphyrinogen colorimetric sensing chromophores: N-alkylation and beta-substitution

Meso-5,10,15,20-tetrakis-3,5-di-tert-butyl-4-oxocyclohexadienylideneporphyrinogen, OxP, is a versatile, highly colored chromophore derived from meso-5,10,15,20-tetrakis(3,5-di-tert-butyl-4-hydroxyphenyl)porphyrin. It exhibits a wide range of chromogenic responses to solvents (solvatochromism), anions and acidic media (halochromism) making it potentially useful as an analytical reagent. The chromogenic responses of OxP can be modulated by varying its chemical structure, and this is reviewed here based on the introduction of substituents at central nitrogen atoms or pyrrolic beta-positions. OxP and its N-alkylated derivates Bn(2)OxP and Bn(4)OxP have been used to estimate acidity in non-polar solvents. Bn(2)OxP can also be used to determine enantiomeric excesses of chiral substances. N-alkylation has also been used to introduce higher functional groups such as porphyrins to prepare self-assembling systems. beta-Substitution has been used to introduce selectivity of anion interactions including towards basic anions (fluoride, cyanide) and polyoxoanions (nitrate, perchlorate, etc.). These aspects make OxP a highly adaptable tetrapyrrole molecule for sensing and other applications.

Squaramide catalyzed alpha-chiral amine synthesis

Enantiomerically pure alpha-chiral amines, have been commonly utilized as resolving agents and chiral auxiliaries and are currently found in 40% of active pharmaceutical ingredients. Hence, development of highly stereoselective metal-free protocols regarding atom-economy and large-scale applications becomes a major issue. In this respect, chiral bifunctional H-bonding squaramides have been successfully applied for both amine synthesis and functionalization of amines in the last decade. This survey summarizes asymmetric synthesis of chiral amines by various carbon-carbon and carbon-nitrogen bond formation with squaramide catalysis as a particular focus of interest.

CNOT gate on reverse photon modes in a ring cavity

Photon modes of the reverse rotation in a ring QED cavity coupled with a single atom are considered. By applying the Schrieffer-Wolf transformation for the off-resonant light-atom interaction, an effective Hamiltonian of the photon modes evolution is obtained. Heisenberg equations for the input-output photon mode operators are written, and the expression for the wave function of the system is found. The analytical solution shows the condition of the control NOT quantum gate implementation on chiral photon modes. A possible on-chip experimental implementation and recommendations for the construction of an optical quantum computer using this gate are considered.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 50893-53-3 is helpful to your research. Product Details of 50893-53-3.

A Photochemical Route to 3-and 4-Hydroxy Derivatives of 2-Aminocyclobutane-1-carboxylic Acid with an all-cis Geometry

Short grain-scale syntheses of both enantiomers of 2-amino-3-hydroxycyclobutane-1-carboxylic acid and of 2-amino-4-hydroxycyclobutanecarboxylic acid with an all-cis geometry are described. The sequences feature highly endo-selective [2 + 2]-photocycloaddition reactions followed by fully regioselective ring opening/Hofmann rearrangement/nitrogen protection, in a consecutive or one-pot protocol, followed by efficient resolution using a chiral oxazolidinone.

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. you can also check out more blogs about 3896-11-5. Computed Properties of C17H18ClN3O.

Stereoselectivity in a nitroso-ene cyclization: Formal synthesis of rac-manzacidins A and C

Nitroso-ene (NE) reactions have been adapted in the construction of nitrogen-containing motifs in many biologically interesting compounds. The transient and highly reactive nitroso species remains a challenge for designing stereocontrolled syntheses. Although chiral auxiliary-based method has been developed to achieve high diastereoselectivity, the use of the inherent chirality of the nitroso compound for stereochemical control remains underdeveloped. We chose the formation of a gamma-lactam via a NE cyclization as a basis to study the applicable principles for future asymmetric syntheses. The selected examples presented herein reveal that the intramolecular hydrogen bond would provide conformational restraint to facilitate excellent facial selectivity in the NE reaction via a chair-like transition state. The sterically bulky amino group also provides excellent stereochemical control possibly through steric repulsion. The following transformations led to a key intermediate (Ohfune’s lactone) in the preparation of manzacidins A and C and thus constitutes a formal synthesis. (C) 2018 Elsevier Ltd.

Aggregation-induced red shift in N,S-doped chiral carbon dot emissions for moisture sensing

Being a promising class of carbogenic nanomaterials with excellent photophysical and photochemical properties, carbon dots (Cdots) have been exploited for multifaceted applications to date. Herein, a facile synthetic approach has been utilized in order to prepare Cdots using the microwave method, which demonstrates the production of crystalline Cdots unifying exceptional properties such as chirality, solvatochromism, and aggregation-induced emission (AIE) with a red shift and a high quantum yield. Our study on the aggregation behaviors of Cdots revealed the coexistence of complex aggregates in our system. AIE induced luminescence color change of the Cdots is demonstrated with the help of chromaticity color coordinates in the CIE diagram and the hue spectrum/histogram using a smartphone. The pronounced AIE effects of Cdots lead to the detection of moisture in various solvents e.g. acetone, acetonitrile, ethanol, THF, DMSO, methanol, and formamide. Remarkably, Cdots are highly responsive for water in acetone solvent with the LOD as low as 8.47 ppm. Furthermore, the Cdots were successfully employed for the detection and quantitative determination of the moisture content in daily used commercial products and drugs. Then, a gel (or fluorescent ink) was also fabricated on a non-fluorescent paper that behaves as a molecular switch showing the reusability of Cdots as moisture sensors for practical applications.

Enantioselective [4+1]-Annulation of alpha,beta-Unsaturated Imines with Allylic Carbonates Catalyzed by a Hybrid P-Chiral Phosphine Oxide-Phosphine

A highly enantio- and diastereoselective [4 + 1]-annulation reaction between alpha,beta-unsaturated imines and allylic carbonates has been realized under the catalysis of a novel hybrid P-chiral phosphine oxide-phosphine, providing enantioenriched polysubstituted 2-pyrrolines in good to excellent yields and up to 99% ee. Based on Han’s methods, the catalyst featuring a sole P(O)-chirality in the molecule is readily accessible and represents a class of new chiral phosphine organocatalysts. In the plausible catalytic mechanism, art intramolecular Coulombic interaction between the in situ generated phosphonium cation and polar chiral P=O moiety may play a positive role.
