标题 :Chemical synthesis of flavipucine
发明人：WENDLER NORMAN L; GIROTRA NARINDAR N; ZELAWSKI ZBIGNIEW S
权利人:MERCK & CO INC
摘要:A method for the total chemical synthesis of flavipucine employs the condensation of 4-hydroxy-6-methyl-2-pyridone with isobutylglyoxal in alkali alkoxide. The resulting alkali salt is acylated in both the 1' and 4 positions. Treatment of the 1',4-diacyloxy derivative with excess alkaline peroxide yields flavipucine.

权利人:NIPPON CATALYTIC CHEM IND
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.

标 题:Method for the synthesis of 2′,3′-dideoxy-2′,3′-didehydronucleosides
发明人：JIN FUQIANG; CONFALONE PASQUALE N
权利人:PHARMASSET LTD
摘要:An efficient synthetic route to antiviral 2′,3′-dideoxy-2′,3′-didehydro-nucleosides, such as 2′,3′-dideoxy and 2′- or 3′-deoxyribo-nucleoside analogs, from available precursors is disclosed, with the option of introducing functionality as needed. In one embodiment, a method for the preparation of β-D and β-L-2′,3′-dideoxy-2′,3′-didehydro-nucleosides is described that includes: activating a compound of structure (1) n n nwherein B is a pyrimidine or purine base and Y is O, S or CH 2 with an acyl halide of the formula X—C(â•?O)R 1 , X—C(â•?O)C(R 1 ) 2 OC(â•?O)R 1 or X—C(â•?O)OR 1 (wherein X is a halogen, and each R 1 is independently hydrogen, lower alkyl, alkyl, aryl or phenyl); reducing the resulting compound with a reducing agent to form a 2′,3′-dideoxy-2′,3′-didehydro-nucleoside; and optionally deprotecting the nucleoside. The haloacylation of the first step can form the 2′-acyl-3′-halonucleoside, the 3′-acyl-2′-halonucleoside, or a mixture thereof.
