- Room-Temperature Palladium(II)-Catalyzed Direct 2-Arylation of Indoles with Tetraarylstannanes
-
A palladium(II)-catalyzed direct 2-arylation of indoles by tetraarylstannanes with oxygen (balloon) as the oxidant at room temperature has been developed. Various tetraarylstannanes can be employed as aryl sources for 2-arylation of indoles in up to 89% yield, providing a practical and efficient catalytic protocol for accessing 2-arylindoles.

- Chromium(II)-Catalyzed Diastereoselective and Chemoselective Csp2-Csp3 Cross-Couplings Using Organomagnesium Reagents
-
A simple protocol for performing chromium-catalyzed highly diastereoselective alkylations of arylmagnesium halides with cyclohexyl iodides at ambient temperature has been developed. Furthermore, this ligand-free CrCl2 enables efficient electrophilic alkenylations of primary, secondary, and tetiary alkylmagnesium halides with readily available alkenyl acetates. Moreover, this chemoselective C-C coupling reaction with stereodefined alkenyl acetates proceeds in a stereoretentive fashion. A wide range of functional groups on alkyl iodides and alkenyl acetates are well tolerated, thus furnishing functionalized Csp2-Csp3 coupling products in good yields and high diastereoselectivity. Detailed mechanistic studies suggest that the in situ generated low-valent chromium(I) species might be the active catalyst for these Csp2-Csp3 cross-couplings.

- SULFONIUM SALT AND PHOTO-ACID GENERATOR
-
Provided is a novel sulfonium salt that has high solubility in a solvent and has high light sensitivity to, especially, light having a wavelength not longer than deep-UV (254 nm) and a novel photo-acid generator comprising the sulfonium salt. The invention relates to a sulfonium salt represented by the following general formula (1) and a novel photo-acid generator comprising the sulfonium salt. wherein R1 represents an electron withdrawing group; R2 and R3 each independently represent an alkyl group having 1 to 5 carbon atoms, an alkoxy group, an acyl group, a halogenated alkyl group, a halogen atom, a hydroxyl group, a cyano group, or a nitro group; p and q each independently represent an integer of 0 to 5; and X? represents a monovalent counter anion.

- Novel tetranuclear triarylantimony(v) complexes with (±)-mandelic acid ligands: Synthesis, characterization, in vitro cytotoxicity and DNA binding properties
-
Four novel tetranuclear organoantimony(v) complexes [R3SbL] 4, in which LH = (±)-mandelic acid and R = phenyl (1), 4-fluorophenyl (2), 3-fluorophenyl (3), 3,4,5-trifluorophenyl (4), were synthesized and characterized. The complexes displayed rapid, low micromolar in vitro cytotoxicity against a range of epithelial tumour cells and efficient CT-DNA binding.

- Heterocyclic compounds as P2X7 ion channel blockers
-
The present invention relates to a novel series of 4,5-diphenyl-2-amino-4,5-dihydro-imidazole derivatives of the formula II: 1 wherein R, R1, R2, R3, R4, R5, X and Y are as defined herein. This invention also relates to methods of making these compounds. The compounds of this invention are P2X7 ion channel blockers and are therefore useful as pharmaceutical agents, especially in the treatment and/or prevention of a variety of diseases having an inflammatory component, including inflammatory bowel disease, rheumatoid arthritis and disease conditions associated with the central nervous system, such as stroke, Alzheimer''s disease, etc.

- Bromine-magnesium-exchange as a general tool for the preparation of polyfunctional aryl and heteroaryl magnesium-reagents
-
The scope of the Br-Mg-exchange reaction for the preparation of polyfunctional aryl and heteroaryl magnesium reagents has been studied. Various functional groups (ester, cyano, bromide) were tolerated in the exchange reaction allowing the preparation of polyfunctional Mg-reagents. Several dibromo- or tribromoheterocycles undergo a chemoselective mono-Br-Mg exchange leading to highly functionalized heterocycles.
