Diastereoselective alkylation of 2,3,4,6-Di-O-isopropylidene-2-keto-L-gulonic amides. Application to the asymmetric synthesis of 1-substituted-1,2,3,4-tetrahydroisoquinolines and 1-substituted-1,2,3,4,-tetrahydro-beta-carbolines

The diastereoselective alkylation of amides 3a,b and 7a,b derived from gulonic acid is described. Substituted compounds are obtained in good yield and high diastereoselectivity. A mechanistic investigation establishes that the diastereoselectivity did not arise from an initial asymmetric deprotonation. The stereochemistry is then determined during the alkylation step.

Highly efficient aerobic ruthenium-catalyzed oxidative cross-dehydrogenative coupling for sp3-sp3 carbon-carbon bond formation

A highly efficient sp3-sp3 carbon-carbon bond formation system was developed for the aerobic ruthenium-catalyzed oxidative cross-dehydrogenative coupling reaction between tertiary amines and sp3 C-H compounds in the presence of RuCl3/O2, thus giving the corresponding alpha-functionalized amines. Compared with the reported method, H2O2 or tBuOOH was replaced successfully by economical and facile oxygen as the oxidant. Three types of activated C-H bonds for pronucleophiles were evaluated in this system. All these features combined are in accordance with important prospective green chemistry aspects.

Exploring the active site of phenylethanolamine N-methyltransferase with 3-hydroxyethyl- and 3-hydroxypropyl-7-substituted-1,2,3,4- tetrahydroisoquinolines

3-Hydroxyethyl- and 3-hydroxypropyl-7-substituted-tetrahydroisoquinolines (9, 10, 16, and 17) were synthesized and evaluated for their phenylethanolamine N-methyltransferase (PNMT) inhibitory potency and affinity for the alpha2-adrenoceptor. Although alpha2-adrenoceptor affinity decreased for these compounds, selectivity was not gained over the parent 3-hydroxymethyl compounds (1, 2) due to a loss in PNMT inhibitory potency.

Monofluoromethylation of tetrahydroisoquinolines by visible-light induced direct C(sp3)-H bond activation

A visible-light photoredox-catalyzed reaction of tetrahydroisoquinolines with beta-fluorinated gem-diols results in the formation of C1-monofluoromethylated tetrahydroisoquinolines via C(sp3)-H bond activation. This protocol provides a new method to introduce a CF group with stable, easily-prepared monofluorinated gem-diol as CF source. A mechanistic investigation is presented based on control experiments.

Search for anticonvulsant and analgesic active derivatives of dihydrofuran-2(3H)-one

A series of derivatives of dihydrofuran-2(3H)-one (gamma-butyrolactone, GBL) was synthesized and tested for anticonvulsant, neurotoxic and analgesic activity. In the anticonvulsant screening 10 lactones were effective in the maximal electroshock test (MES) at the highest doses (300 and 100 mg/kg, 0.5 h, ip, mice). Statistical analysis showed correlation between the anticonvulsant activity and relative lipophilicity parameters determined by experimental and computational methods (RM0, C log P and M log P). Preliminary antinociceptive evaluation of selected derivatives revealed strong analgesic activity. The majority of the tested compounds showed high efficacy in animal models of acute pain (hot plate and writhing tests) and strong local anesthetic activity (modified tail immersion test). The obtained ED50 values were comparable with such analgesics as acetylsalicylic acid and morphine.

TiO2 Nanoparticles Functionalized with Non-innocent Ligands Allow Oxidative Photocyanation of Amines with Visible/Near-Infrared Photons

Photosynthesis is an efficient mechanism for converting solar light energy into chemical energy. We report on a strategy for the aerobic photocyanation of tertiary amines with visible and near-infrared (NIR) light. Panchromatic sensitization was achieved by functionalizing TiO2 with a 2-methylisoquinolinium chromophore, which captures essential features of the extended ?-system of 2,7-diazapyrenium (DAP2+) dications or graphitic carbon nitride. Two phenolic hydroxy groups make this ligand highly redox-active and allow for efficient surface binding and enhanced electron transfer to the TiO2 surface. Non-innocent ligands have energetically accessible levels that allow redox reactions to change their charge state. Thus, the conduction band is sufficiently high to allow photochemical reduction of molecular oxygen, even with NIR light. The catalytic performance (up to 90% chemical yield for NIR excitation) of this panchromatic photocatalyst is superior to that of all photocatalysts known thus far, enabling oxidative cyanation reactions to the corresponding alpha-cyanated amines to proceed with high efficiency. The discovery that the surface-binding of redox-active ligands exhibits enhanced light-harvesting in the red and NIR region opens up the way to improve the overall yields in heterogeneous photocatalytic reactions. Thus, this class of functionalized semiconductors provides the basis for the design of new photocatalysts containing non-innocent donor ligands. This should increase the molar extinction coefficient, permitting a reduction of nanoparticle catalyst concentration and an increase of the chemical yields in photocatalytic reactions.

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 1612-65-3 is helpful to your research. Related Products of 1612-65-3

Synthesis, structures and luminescent properties of cadmium(ii) metal organic frameworks based on 3-pyrid-4-ylbenzoic acid, 4-pyrid-4-ylbenzoic acid ligands

Two three-dimensional metal-organic frameworks, [Cd3K(L 1)6(H2O)3](OH)(DMF)4 (1) (HL1 = 3-pyrid-4-ylbenzoic acid) and [Cd(L2) 2](DMF)(H2O)0.25 (2) (HL2 = 4-pyrid-4-ylbenzoic acid), have been synthesized by using two ligands with different configuration and characterized by X-Ray diffraction and other techniques. Compound 1 shows a nanosize channel which is constructed by interlocked six-fold one-dimensional helical chains with the asymmetrical ligand HL1. Compared with compound 1, compound 2 shows a larger size channel with the symmetrical ligand HL2 in a single set of diamond cage. Nevertheless, the whole structure with the 4-fold interpenetrated diamondoid network leads to the absence of void space. The two compounds exhibit fascinating luminescence because of the interaction between Cd ions and organic ligands. The Royal Society of Chemistry 2012.

Isoquinoline-N-Boranes as Precursors to Substituted Tetrahydroisoquinolines

A new approach to the syntheses of 1,2-disubstituted 1,2,3,4-tetrahydroisoquinolines from isoquinoline-N-boranes is described.The method is a “one-pot” operation in which substituents are introduced consecutively as electrophiles and nucleophiles with accompanying reduction of the heterocyclic ring.This procedure differs from the classical ones in that both requisite rings are present in the starting material and thus avoids the inefficient cyclizations of phenethylamine derivatives when unactivated substrates would be required.The synthetic utility of this process is demonstrated with several examples including the alkaloids carnegine and hydrohydrastinine.
