Utilization of optically active secondary phosphine-boranes: synthesis of P-chiral diphosphines and their enantioinduction ability in rhodium-catalyzed asymmetric hydrogenation

Abstract Both enantiomers of tert-butylmethylphosphine-borane have been used for the synthesis of P-chiral diphosphines and/or their borane complexes. The enantiopure borane complex of 1,2-bis(tert-butylmethylphosphino)ethane (t-Bu-BisP?) was prepared in high yield from the secondary phosphine-borane and 1,2-dichloroethane. A mono-chelated Rh-complex of t-Bu-MiniPHOS was prepared and its catalytic activity was examined in the asymmetric hydrogenation of some representative functionalized alkenes. Synthesis of three new P-chiral phosphine ligands with quinoline or quinoxaline backbone is also described together with their enantioinduction ability.

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.Application In Synthesis of 2,3-Dichloroquinoxaline, you can also check out more blogs about2213-63-0

Identification of novel lysine demethylase 5-selective inhibitors by inhibitor-based fragment merging strategy

Histone lysine demethylases (KDMs) have drawn much attention as targets of therapeutic agents. KDM5 proteins, which are Fe(II)/alpha-ketoglutarate-dependent demethylases, are associated with oncogenesis and drug resistance in cancer cells, and KDM5-selective inhibitors are expected to be anticancer drugs. However, few cell-active KDM5 inhibitors have been reported and there is an obvious need to discover more. In this study, we pursued the identification of highly potent and cell-active KDM5-selective inhibitors. Based on the reported KDM5 inhibitors, we designed several compounds by strategically merging two fragments for competitive inhibition with alpha-ketoglutarate and for KDM5-selective inhibition. Among them, compounds 10 and 13, which have a 3-cyano pyrazolo[1,5-a]pyrimidin-7-one scaffold, exhibited strong KDM5-inhibitory activity and significant KDM5 selectivity. In cellular assays using human lung cancer cell line A549, 10 and 13 increased the levels of trimethylated lysine 4 on histone H3, which is a specific substrate of KDM5s, and induced growth inhibition of A549 cells. These results should provide a basis for the development of cell-active KDM5 inhibitors to highlight the validity of our inhibitor-based fragment merging strategy.

PHOTOLYTIC RING-EXPANSIONS OF 4-AZIDOQUINOLINES AND 6-AZIDODIAZINES: SOME UNEXPECTED AZEPINE RING-OPENING REACTIONS

Photolysis of 6-azidoquinazoline in MeOH-KOMe-dioxan yields 8,9-dihydro-5,7-dimethoxy-5H-pyrimido<5,4-c>azepine (5) which on acid hydrolysis ring-opens to the pyrimidine-carbaldehyde (7).The mechanism of formation of this unexpected dimethoxypyrimido-azepine is discussed and related to previous similar results involving 6-azido-2,3-dihydrofuro- and 6-azido-2,3-dihydrothieno<2,3-b>quinolines. In contrast, 6-azidoquinoxaline and 6-azido-2-chloro-4-methylquinoline on photolysis under similar conditions undergo ring expansion to the expected pyrazino<2,3-c>– and pyrido<3,2-c>azepines (22a) and (17) respectively.However, photolysis of the latter azide in MeOH-dioxan yields the 3-(2-pyridyl)propenonitrile derivative (18) in a reaction analogous to that undergone by 6-azidophenazine.

Synthesis and preliminary biological evaluation of potent and selective 2-(3-alkoxy-1-azetidinyl) quinolines as novel PDE10A inhibitors with improved solubility

We report the discovery of a novel series of 2-(3-alkoxy-1-azetidinyl) quinolines as potent and selective PDE10A inhibitors. Structure-activity studies improved the solubility (pH 7.4) and maintained high PDE10A activity compared to initial lead compound 3, with select compounds demonstrating good oral bioavailability. X-ray crystallographic studies revealed two distinct binding modes to the catalytic site of the PDE10A enzyme. An ex vivo receptor occupancy assay in rats demonstrated that this series of compounds covered the target within the striatum.

One-Pot and Three-Component Synthesis of Furopyridoquinoxaline Derivatives under Catalyst-Free Conditions

A series of 11-aryl-8,11-dihydrofuro[3′,4′:5,6]pyrido[3,2-f]quinoxalin-10(7H)-one derivatives were obtained via a one-pot and three-component reaction of aromatic aldehydes, 6-aminoquinoxaline and tetronic acid in EtOH. The structure of 11-(4-nitrophenyl)-8,11-dihydrofuro[3′,4′:5,6]pyrido[3,2-f]quinoxalin-10(7H)-one (4g) was confirmed by X-ray diffraction analysis.
