摘要:A catalyst for producing an aryl ester of a carbonic or carboxylic acid is disclosed, which includes a microporous material containing a metal element belonging to group IV. This catalyst can be used as a heterogeneous catalyst to produce the aryl ester in high yield with industrial advantages. In order to produce the aryl ester using the catalyst, a carbonate or an aliphatic carboxylate is transesterified with an aromatic hydroxy compound, or an aryl carboxylate is transesterified with a carbonate, or an alkyl aryl carbonate is disproportionated by transesterification.

摘要:PCT No. PCT/US93/00211 Sec. 371 Date Jul. 25, 1994 Sec. 102(e) Date Jul. 25, 1994 PCT Filed Jan. 26, 1993 PCT Pub. No. WO93/15103 PCT Pub. Date Aug. 5, 1993.Novel steroids having a 9 alpha -hydroxy or a 9 alpha -carbonate substituent can be prepared from 9 alpha -hydroxyandrostenedione and can be utilized in the synthesis of commercially valuable corticosteroids such as betamethasone. The 9 alpha -carbonates are prepared by reaction of the corresponding 9 alpha -hydroxy steroid with a sequence of excess base, trialkylsilyl chloride, alkyl haloformate and alkanol or by using excess base, alkyl haloformate and alkoxide. 9 alpha -Carbonate-17-keto compounds can be treated with lithium acetylide and a lithium salt to afford the corresponding 17 alpha -ethynyl-17 beta -hydroxy-9 alpha -carbonate. This compound is then esterified with a novel series of reagents to give the 17-ester which can be reduced the corresponding 17-allene. Oxidation of this allene to the bis-epoxide compound, followed by treatment with an alkali metal salt of a carboxylic acid under phase transfer conditions gives the 17 alpha -hydroxy 21-ester 9 alpha -carbonate. Elimination of the 9 alpha -carbonate group affords the a 17 alpha -hydroxy, 9(11)ene, which in a few subsequent steps can be converted to a variety of commercially important corticosteroids. Novel 9 alpha -carbonate compounds are prepared in the various reaction steps.

摘要:Saxitoxin analog compounds, compositions, pharmaceutical compositions, methods of synthesis of saxitoxin analogs, methods of imaging, methods of treatment, including methods of treating pain, are provided. Saxitoxin (STX), gonyautoxin (GTX), and zetekitoxin, and variant STX compounds bind to sodium channels and are effective to reduce or block flow of sodium ions through such channels. Such channel block affects nerve and muscle action, and may be effective to reduce or block pain sensations, relax muscles, reduce muscle spasm, and reduce wrinkles. STX analog binding to sodium channels may also be useful to locate, image, or mark sodium channels, and so be useful in studying sodium channels and sodium channel disorders, and in the diagnosis and treatment of patients suffering from sodium channel disorders. In embodiments, the variant STX compounds include conjugates having increased serum half-life as compared to STX when administered to a subject. n In embodiments, the present disclosure provides a method for alleviating pain in a subject in need of treatment, the method comprising administering to the subject an effective amount of a saxitoxin analog compound, or a pharmaceutically acceptable salt, isomer, tautomer or prodrug thereof, whereby pain in said subject is alleviated.
