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.

标 题 :Dihydropyridinones and pyrrolinones useful as alpha 1A adrenoceptor antagonists
发明人：BARROW JAMES C; NANTERMENT PHILIPPE G; SELNICK HAROLD G
权利人:MERCK & CO INC
摘要:Novel dihydropyridinone and pyrrolinone compounds and pharmaceutically acceptable salts thereof are disclosed. The synthesis of these compounds and their use as alpha 1a adrenergic receptor antagonists is also described. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia can be achieved.
