Quinazoline deriviates for treating peptic ulcer

A quinazoline derivative represented by formula(I) or a pharmaceutically acceptable salt thereof is useful for the treatment of peptic ulcer, wherein: STR1 R1 and R2 are each hydrogen or a C1 -C4 alkyl group; R3 is hydrogen or a halogen; R4, R5, R6, R7, R8 and R9, which may be the same or different, are each hydrogen, a C1 -C4 alkyl group, a cyclopropyl group, or a C1 -C4 alkyl group substituted with a halogen; and R10 is a methoxy group.

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.Recommanded Product: 3-Methylisoquinoline, you can also check out more blogs about1125-80-0

New N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines as leads to potential PET radioligands for imaging the open NMDA receptor

An expansive set of N-aryl-N?-(3-(substituted)phenyl)-N?-methylguanidines was prepared in a search for new leads to prospective PET ligands for imaging of the open channel of the N-methyl-d-aspartate (NMDA) receptor in vivo. The N-aryl rings and their substituents were varied, whereas the N-methyl group was maintained as a site for potential labeling with the positron-emitter, carbon-11 (t1/2 = 20.4 min). At micromolar concentration, over half of the prepared compounds strongly inhibited the binding of [3H]TCP to its binding site in the open NMDA receptor in vitro. Four ligands displayed affinities that are similar or superior to those of the promising SPECT radioligand ([123I]CNS1261). The 3?-dimethylamino (19; Ki 36.7 nM), 3?-trifluoromethyl (20; Ki 18.3 nM) and 3?-methylthio (2; Ki 39.8 nM) derivatives of N-1-naphthyl-N?-(phenyl)-N?-methylguanidine were identified as especially attractive leads for PET radioligand development.

Visible light-induced direct alpha C?H functionalization of alcohols

Considering the synthetic value of introducing active alcoholic hydroxyl group, developing C?H functionalization of alcohols is of significance. Herein, we present a photochemical method that under visible light irradiation, selectfluor can effectively promote the oxidative cross-coupling between alcohols and heteroarenes without the external photocatalysis, achieving the selective alpha sp3 C?H arylation of alcohol, even in the presence of ether. The N-F activation of selectfluor under blue LEDs irradiation is evidenced by electron paramagnetic resonance (EPR) study, which is the key process for the oxidative activation of alpha sp3 C?H alcohols. The observed reactivity may have significant implications for chemical transformations.

C-10 ester and ether derivatives of dihydroartemisinin – 10-alpha artesunate, preparation of authentic 10-beta artesunate, and of other ester and ether derivatives bearing potential aromatic intercalating groups at C-10

Preparative and stereochemical aspects of reactions providing new C-10 ester and ether derivatives of the antimalarial drug dihydroartemisinin (DHA, 2) have been examined. beta-Artesunate has been prepared for the first time, and has been differentiated from the antimalarial alpha-artesunate; the latter has been incorrectly designated as the beta-epimer in Chemical Abstracts and some primary literature. New ester and ether derivatives bearing potential intercalating groups have been synthesised by means of the Schmidt, Mitsunobu and DCC coupling procedures, by acylation in the presence of DMAP, or by hydroxy activation with BF3 as catalyst. When the hydroxy group of DHA acts as a nucleophile towards activated carboxy groups in acylating agents or the DCC intermediate, alpha-esters are obtained exclusively. When the hydroxy group is activated for displacement by nucleophiles, as in the Schmidt or Mitsunobu procedures, beta-esters and beta-ethers are obtained either exclusively or predominantly. An exception is represented by the Mitsunobu procedure involving DHA and 1- and 2-naphthols, in which mixtures of epimers are obtained; however, exclusive formation of beta-aryl ethers takes place when the Schmidt procedure is used, with activation of the intermediate trichloracetimidate by SnCl2. The latter method is therefore superior to patented procedures for the preparation of beta-aryl ethers from nonbasic aryl alcohols without detectable rearrangement to C-aryl compounds. However, the Mitsunobu procedure is better when basic aromatic alcohols are used as nucleophiles. The formation of alpha-products in which the hydroxy group of DHA acts as a nucleophile is of biological significance in relation to enzyme-mediated Phase II glucuronidation of DHA, in which only the alpha-DHA glucuronide is formed.

One-pot alpha-arylation of beta-carboline with indole and naphthol derivatives

4,9-Dihydro-3H-beta-carboline and 6-methoxy-4,9-dihydro-3H-beta-carboline were subjected to catalyst-free one-pot alpha-arylation with 1-or 2-naphthol, 6-hydroxyquinoline or 5-hydroxyisoquinoline as N-containing analogues via direct aza-Friedel-Crafts reactions. The procedure was then extended to other electron-rich aromatic compounds, such as indole or indole-2-carboxylic acid, to yield new indole gamma-amino acid derivatives containing beta-carboline skeleton. All the reactions were performed both under neat conditions and with microwave irradiation. The reaction of 2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole and benzaldehyde with 1-naphthol as nucleophile led to the formation of the N-alkylated compound as a single product, whereas the reaction with 2-naphtol resulted in the two possible alpha-arylated/N-alkylated products, in a ratio depending on the reaction conditions.

Quantum Dots in Visible-Light Photoredox Catalysis: Reductive Dehalogenations and C-H Arylation Reactions Using Aryl Bromides

In the recent past, visible-light-mediated photoredox catalysis has made a huge impact on the development of new synthetic methods under very mild and ecologically benign conditions. Although semiconductor nanocrystals or quantum dots (QDs) possess suitable optoelectronic and redox properties for photoredox catalytic applications, surprisingly, their use for the activation of challenging chemical bonds in the synthesis of organic molecules is little explored. We report here the application of ZnSe/CdS core/shell QDs for the synthetically important photoredox catalytic activation of carbon-halogen bonds in dehalogenation and C-H arylation reactions using (hetero)aryl halides as bench-stable inexpensive bulk starting materials, under very mild reaction conditions. The outstanding catalytic activity of ZnSe/CdS core/shell QDs is a direct consequence of the high specific surface area and homogeneity of QDs in solution and their high photostability toward oxidation.

Suzuki-Miyaura cross-coupling for efficient synthesis of aryl-substituted N-heteroarenes catalyzed by recyclable N-phenylpiperazine-Palladium(II) complex

Polystyrene supported N-phenylpiperazine-Pd(II) complex D was synthesized and characterized by various techniques, including Fourier transform infrared spectroscopy (FTIR), scanning electronmicroscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and thermal analysis (TG-DTA). This heterogeneous Pd(II) complex showed high catalytic efficiency for the Suzuki-Miyaura coupling of arylboronic acids with aryl bromides, aryl chlorides to give the corresponding 2-arylpyridines and heteroarenes. The coupled products were formed in excellent yields at low catalyst loadings under mild reaction conditions. Further, this heterogeneous catalyst showed excellent recyclability and reused for four cycles with no significant decrease in its activity.

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 1532-71-4 is helpful to your research. Application of 1532-71-4
