标题 :Aryloxime linkers in the solid-phase synthesis of 3-aminobenzisoxazoles
发明人：WILEY MICHAEL ROBERT; LEPORE SALVATORE DONATO
权利人:LILLY CO ELI; WILEY MICHAEL ROBERT; LEPORE SALVATORE DONATO
摘要:In its first aspect, the invention is directed to a solid support mediated method for the synthesis of diverse polycyclic heterocycles according to general formula (V). A second aspect of the invention is directed to a solid support bound intermediate compound that optionally can be derivatized before a cyclization and displacement procedure provides a product. The intermediate is preferably stable to a wide range of chemical conditions thus allowing, if desired, for the chemical derivatization of the intermediate. A third aspect of the invention is directed to a library of polycyclic heterocycle compounds where said library contains a plurality of diverse library compounds of general formula (V). A fourth aspect of the invention is directed to a method for the synthesis of a library of diverse polycyclic heterocycles by the general method described. A fifth aspect of the invention is directed to an assay kit for the identification of lead compounds of the library described therein.

标题:Fluorinated silica catalyst and preparation of aromatic/aliphatic nitriles in the presence thereof
发明人：JACQUES ROLAND; REPPELIN MICHEL; SEIGNEURIN LAURENT
权利人:RHONE POULENC SPEC CHIM
摘要:An improved fluorinated siliceous catalyst, well adapted for the catalytic synthesis of aromatic/aliphatic nitriles from their corresponding formamides, formanilides or amides, is comprised of a plurality of silica particulates, the specific surface of which ranging from about 200 to about 300 m 2 /g, having a total pore volume ranging from about 1 to about 1.5 cm 3 /g, with an average pore diameter ranging from about 100 to about 200 â„«, having an exchange pH of less than about 3, and with the fluorine content thereof bonded to the silica, expressed in F 31 , ranging from about 0.05 to about 2% by weight based upon the silica, and the sodium content thereof, expressed as Na 2 O, being less than about 1% by weight, also based upon the silica.

权利人:MERCK & CO INC; LYNCH JOSEPH E; SHI YAO JUN; WELLS KENNETH M
摘要:The invention provides a process for regioselective substitution of trifluorobenzoate/trifluorobenzonitrile to afford the difluorobenzoate/difluorobenzonitrile in good yields. The resulting difluorobenzoate/difluorobenzonitrile can again be regioselectively substituted with a second nucleophile to give monofluorobenzoate/monofluorobenzonitrile also in good yields. This process is particularly useful for forming key intermediates in the synthesis of oxytocin antagonist compounds.
