Selective introduction of fluorine into molecules by the cleavage of inert C?H bonds is of central academic and synthetic interest, yet remains challenging. Given the central role of alcohols in organic chemistry as the most ubiquitous building blocks, a versatile and selective C(sp3)?H and C(sp2)?H fluorination of simple alcohols, enabled by novel designed exo-directing groups, is described. C(sp2)?H bond fluorination was achieved by using a simple acetone oxime as auxiliary, whereas a new, modular and easily accessible bidentate auxiliary was developed for the efficient and site-selective fluorination of various primary methyl, methylene, and benzylic C(sp3)?H bonds. Fluorinated alcohols can readily be accessed by the removal of auxiliaries, and significantly expands the synthetic prospect of the present procedure.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. Application of 22013-33-8

Certain novel substituted imidazole 4-carboxamides are ligands of the human cholecystokinin receptor and, in particular, are selective ligands of the human cholecystokinin-1 receptor (CCK-1R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the modulation of CCK-1R, such as obesity, and diabetes.

The design and synthesis of related molecules that are more effective, more selective, and less toxic than aspirin are important objectives of biomedical research.Keep reading other articles of 22013-33-8Application of 22013-33-8, .

beta-Phenylethylidenehydrazine (PEH) has been demonstrated previously to be an inhibitor of gamma-aminobutyric acid transaminase (GABA-T) and to cause a marked increase in rat brain levels of GABA, a major neurotransmitter. A group of PEH analogs, possessing a variety of substituents (Me, OMe, Cl, F, and CF3) at the 2-, 3-, and 4-positions of the phenyl ring, were synthesized for evaluation as inhibitors of GABA-T. The details of the synthesis and chemical characterization of the analogs are described. Preliminary in vitro screening for GABA-T inhibition showed that all the analogs possessed activity against this enzyme, although substitution of CF3 at the 2- and 4-positions caused reduced activity. One of the drugs, 4-fluoro-beta- phenylethylidenehydrazine, was investigated further ex vivo, where it was shown to inhibit GABA-T, elevate brain levels of GABA, and decrease levels of glutamine, similar to the profile observed previously for PEH.

[Problem] To provide a compound which may be used for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).[Means for Resolution] It was found that a pyrrole derivative characterized by the possession of a guanidinocarbonyl group or amido group as a substituent group at the 3-position, or a pharmaceutically acceptable salt thereof, has a strong antagonism for both of the 5-HT2B receptor and 5-HT7 receptor. In addition, the compound of the present invention having the antagonistic activity for both of the receptors showed a good pharmacological action in comparison with the case in which an antagonist selective for either one of the receptors was used alone. Based on the above, the compound of the present invention is useful for the prevention and/or treatment of diseases in which 5-HT2B receptor and 5-HT7 receptor are concerned, particularly for the treatment of irritable bowel syndrome (IBS).

A mild protocol has been developed for the PdII-catalyzed alkoxycarbonylation of terminal olefins to produce alpha,beta-unsaturated esters with a wide range of substrates. Key features are the use of MeCN as solvent (and/or ligand) to control the reactivity of the intermediate Pd complexes and the combination of CO with O2, which facilitates the CuII-mediated reoxidation of the Pd0 complex to Pd II and prevents double carbonylation.
