A general and efficient 2-amination of pyridines and quinolines

(Chemical Equation Presented) Pyridine N-oxides were converted to 2-aminopyridines in a one-pot fashion using Ts2O-t-BuNH2 followed by in situ deprotection with TFA. The amination proceeded in high yields, excellent 2-/4-selectivity, and with good functional group compatibility. 2-Amino (iso)quinolines were also obtained in the same manner. Combined with the simple oxidation of pyridines to pyridine N-oxides, this method provides a general and efficient way for amination of 2-unsubstituted pyridines.

Strategies to improve bioavailability and in vivo efficacy of the endogenous opioid peptides endomorphin-1 and endomorphin-2

Morphine and the other alkaloids found in the opium poppy plant still represent the preferred therapeutic tools to treat severe pain in first aid protocols, as well as chronic pain. The use of the opiate alkaloids is accompanied by several unwanted side effects; additionally, some forms of pain are resistant to standard treatments (e.g. neuropathic pain from cancer). For these reasons, there is currently renewed interest in the design and assay of modified versions of the potent endogenous opioid peptides endomorphin-1 and endomorphin-2. This review presents a selection of the strategies directed at preparing highly stable peptidomimetics of the endomorphins, and of the strategies aimed at improving central nervous system bioavailability, for which increased in vivo antinociceptive efficacy was clearly demonstrated.

Synthesis of a water-soluble cationic chiral diamine ligand bearing a diguanidinium and application in asymmetric transfer hydrogenation

A novel water-soluble cationic N-monosulfonated chiral diamine ligand diguanidinium 1c was easily prepared from (R,R)-DPEN and its rhodium complex and was successfully applied in the asymmetric transfer hydrogenation of prochiral ketones and imines in water by using sodium formate and formic acid as co-hydrogen donors. Various substrates were reduced with high yields and good to excellent enantioselectivities (up to >99% ee).

Butyltriphenylphosphonium tetraborate (BTPPTB) as a selective reducing agent for the reduction of imines, enamines and oximes and reductive alkylation of aldehydes or ketones with primary amines in methanol or under solid-phase conditions

Butyltriphenylphosphonium tetraborate (BTPPTB) 1, generated as white solid from butyltriphenylphosphonium bromide and sodium borohydride, is found to be a selective and versatile reducing agent. The reagent in methanol or under solvent-free conditions is very useful for the reduction of imines, enamines and oximes or reductive amination of aldehydes and ketones. Under solvent-free conditions the reactions are faster and the yields of the products are higher.

Biocatalytic oxidation of 2-methylquinoxaline to 2-quinoxalinecarboxylic acid

A microbial process using the fungus Absidia repens ATCC 14849 is described for the oxidation of 2-methylquinoxaline to 2-quinoxalinecarboxylic acid. A campaign consisting of three 14000-L runs produced 20.5 kg of the acid with a 28% overall yield. The bioconversion gave a lower yield compared with a three step chemical synthesis (35%), but was carried out in one pot, and avoided safety issues with a di-N-oxide intermediate. Although successfully scaled to produce kilograms of 2-quinoxalinecarboxylic acid for synthesis of a drug candidate, the A. repens bioconversion is unsuitable for further scale-up due to low product concentration (?1 g/L). A second microbial process using Pseudomonas putida ATCC 33015 is also described for the oxidation of 2-methylquinoxaline. The P. putida bioconversion gave an 86% in situ yield at 8-L scale and yielded a product concentration approximately 10-fold greater than that of the A. repens bioconversion.

Direct Arylation of Unactivated Alkanes with Heteroarenes by Visible-Light Catalysis

The functionalization of aliphatic C-H bonds is both a major challenge and a desirable goal in organic synthesis. Here, we describe the successful arylation of unactivated alkanes with heteroarenes by using iridium polypyridyl complexes as the photocatalyst and persulfate as the HAT catalyst precursor under visible-light irradiation. This reaction features good functional group tolerance and broad scope with regard to both alkane and heteroarene substrates (37 examples), which allows direct access to alkyl-substituted N-heteroarenes, a key structural motif in natural products and bioactive molecules.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. SDS of cas: 80278-67-7, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 80278-67-7, in my other articles.

Synthesis and evaluation of 6-heteroarylamino-2,4,5-trimethylpyridin-3-ols as inhibitors of TNF-alpha-induced cell adhesion and inflammatory bowel disease

Inflammatory bowel disease (IBD) is an inflammatory disease of the gastrointestinal tract with complex pathogenesis. Here, we synthesized 6-heteroarylamino analogues to inhibit TNF-alpha-induced adhesion of monocytes to colon epithelial cells which are implicated in the initial inflammation process of IBD. The best analogue, 16a, showed IC50 = 0.29 muM, which is about five orders of magnitude better than that of 5-aminosalicylic acid (5-ASA), a positive control. Oral administration of 6f and 16a dramatically ameliorated 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colon inflammation in rat. The ameliorating effects were accompanied by a high level of recovery in colon and body weights and in the myeloperoxidase (MPO) level. Consistently, the compounds suppressed the expression of intercellular adhesion molecule-1 (ICAM-1) and monocyte chemoattractant protein 1 (MCP-1). Moreover, they significantly suppressed the expression of pro-inflammatory cytokines such as TNF-alpha, IL-1beta, and IL-6 while increasing the level of IL-10, an anti-inflammatory cytokine.

HALO DERIVATIVES OF 8-AZA-D-HOMOGONANES

A simple one-stage method was developed for synthesizing 15,17-dihalo and 17-halo derivatives of 16,16-dimethyl-8-aza-D-homogona-1,3,5(10),13-tetraene-12,17a-diones.The reaction proceeds regio- and stereoselectively, yielding 17-halo derivatives of 8-aza-D-homogonanes from 4-halo-2-acetyldimedones and 15,17-dichloro derivative from 4,6-dichloro-2-acetyldimedone.The 17-halo derivatives exist in solutions as a mixture of cis and trans isomers at C17 with respect to C9H as a result of keto-enol equilibrium at C17a.In the crystalline state only the trans isomer occurs.In the presence of acids an enolimmonium derivatives with trans arrangement of the halogen at C17 and C9H is formed, which exists only in solution.We isolated, together with the 15,17-dihalo derivative, a mino product, which was assigned the structure of cyclopropano<2',3':15,16>-8-azogonane on the basis of physicochemical data.
