A new imine reductase from Stackebrandtia nassauensis (SnIR) was identified, which displayed over 25- to 1400-fold greater catalytic efficiency for 1-methyl-3,4-dihydroisoquinoline (1-Me DHIQ) compared to other imine reductases reported. Subsequently, an efficient SnIR-catalyzed process was developed by simply optimizing the amount of cosolvent, and up to 15 g L-1 1-Me DHIQ was converted completely without a feeding strategy. Furthermore, the reaction proceeded well for a panel of dihydroisoquinolines, affording the corresponding tetrahydroisoquinolines (mostly in S-configuration) in good yields (up to 81%) and with moderate to excellent enantioselectivities (up to 99% ee).

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 118864-75-8 is helpful to your research. Related Products of 118864-75-8

We report on the optimization of an artificial imine reductase based on the biotin-streptavidin technology. With the aim of rapidly generating chemical diversity, a novel strategy for the formation and evaluation of biotinylated complexes is disclosed. Tethering the biotin-anchor to the Cp* moiety leaves three free coordination sites on a d6 metal for the introduction of chemical diversity by coordination of a variety of ligands. To test the concept, 34 bidentate ligands were screened and a selection of the 6 best was tested in the presence of 21 streptavidin (Sav) isoforms for the asymmetric imine reduction by the resulting three legged piano stool complexes. Enantiopure alpha-amino amides were identified as promising bidentate ligands: up to 63 % ee and 190 turnovers were obtained in the formation of 1-phenyl-1,2,3,4-tetrahydroisoquinoline with [IrCp*biotin(L-ThrNH2)Cl]?SavWT as a catalyst. Biotinspired! A new strategy for the generation of chemical diversity in artificial transfer hydrogenases (ATHases) based on the biotin-streptavidin technology is disclosed. By combining a biotinylated MCp* fragment with 34 commercially available ligands in the presence of wild-type streptavidin, promising candidates for the asymmetric reduction of imines are identified. Selected ligands are screened against 21 streptavidin isoforms and the performance of the resulting constructs is evaluated.

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.SDS of cas: 118864-75-8, you can also check out more blogs about118864-75-8

New chiral isoquinolinium salt derivatives 1, 2 or 3 have been treated with Grignard reagents to give as major products, 1-substituted 1,2-dihydroisoquinolines 4a-f, oxazolidine derivatives 10a-f or 21, respectively, in good yield and in moderate to good diastereoisomeric excess. The stereochemistry of these new derivatives has been elucidated, in particular, by X-ray crystallographic studies of 1,2-dihydroisoquinoline 4b and the minor oxazolidine lib. Reduction of all these intermediates gave chiral 1-substituted 1,2,3,4-tetrahydroisoquinolines such as base 8. The enantioselective synthesis of the natural alkaloid (-)-salsonidine in three steps and 38% overall yield from salt 3 is described as an application. Reduction of salt 2 gave a new oxazolidine derivative 15 which is a practical intermediate for the synthesis of 3-alkyl 1,2,3,4-tetrahydroisoquinolines 17a,b, while oxazolidines such as 10 are convenient precursors of 1,3-disubstituted tetrahydroisoquinolines, as illustrated by a synthesis of 1,3-dimethyl tetrahydroisoquinoline 20.

An innovative development of chemical pathway regarding N-alkylation reaction carried out by adding and recycling only catalytic amount of Hydrotalcite as solid base instead of stoichiometric amount, as per prior art techniques, has attempted. Synthesis of 3 amines, important Active Pharmaceutical Ingredients (APIs) and their intermediates, maintaining the same quality attributes resulting in to minimum generation of carbon dioxide are described. These concept is designed, synthesized, characterized, quantified and compared using ?Carbon Efficiency?, a Green Chemistry Metrics, with already reported work to prove its sustainability. It is industrially advantageous by getting improvement in carbon efficiency and yield as outcome. Here we show a practical greener approach towards Carbon ?

Artificial metalloenzymes, resulting from incorporation of a metal cofactor within a host protein, have received increasing attention in the last decade. The directed evolution is presented of an artificial transfer hydrogenase (ATHase) based on the biotin-streptavidin technology using a straightforward procedure allowing screening in cell-free extracts. Two streptavidin isoforms were yielded with improved catalytic activity and selectivity for the reduction of cyclic imines. The evolved ATHases were stable under biphasic catalytic conditions. The X-ray structure analysis reveals that introducing bulky residues within the active site results in flexibility changes of the cofactor, thus increasing exposure of the metal to the protein surface and leading to a reversal of enantioselectivity. This hypothesis was confirmed by a multiscale approach based mostly on molecular dynamics and protein?ligand dockings.

In lead optimization efforts starting from the tetrahydroisoquinoline (S)-1, we identified 2-{[(2R)-2-hydroxypropyl]amino}-1-[(1S)-8-methoxy-1-phenyl-3,4-dihydroisoquinolin-2(1H)-yl]ethanone ((1S)-8t) as a novel orally active small-molecule N-type calcium channel blocker without CYP inhibition liability. CYP3A4 inhibition profile was improved by reducing the lipophilicity of compound (S)-1. Moreover, introduction of a methoxy group to the C-8 position of tetrahydroisoquinoline led to identification of (1S)-8t, which eliminated CYP2D6 inhibition liability. Oral administration of (1S)-8t exerted efficacy in a rat spinal nerve ligation (SNL) model of neuropathic pain with an ED50 value of 2.8 mg/kg.
