An exemplary thermolabile hydroxyl-protected alcohol is represented by the formula Pg-O—R, wherein Pg is a protecting group of the formula: (Formula) wherein: A is a 2-pyridyl; Z is ... 06/22/06 - 20060135760 - Process for purifying oligonucleotide synthons A process for the purification of an oligonucleotide synthon is provided. The process comprises subjecting an organic solution comprising an oligonucleotide synthon and lower molecular weight impurities to nanofiltration whereby the ratio of an oligonucleotide synthon to lower molecular weight impurities in the solution is increased after the nanofiltration. Preferably, ... 05/04/06 - 20060094869 - Selective process for producing an anomer of a 1-phosphorylated saccharide derivative and process for producing a nucleoside A desired isomer is selectively prepared by phosphorolyzing and isomerizing an anomer mixture of a 1-phosphorylated saccharide derivative while crystallizing one of the isomers to displace the equilibrium. Furthermore, using the action of a nucleoside phosphorylase, a nucleoside is prepared from the 1-phosphorylated saccharide derivative obtained and a base with ... 01/19/06 - 20060014943 - Process for the synthesis of pyrazolopyrimidines The present invention provides a nucleoside comprising a pyrazolopyrimidine base and a process for producing the same. In particular, the processes of the present invention comprises using a halogenated pyrazolopyrimidine base and removing the halogen after the base is coupled to a sugar moiety. The presence of the halogen on ... 12/29/05 - 20050288499 - Modified guanosines having flavouring activity Guano sine-5′-monophosphate derivatives of general formula (I), wherein R, M, x and n have the meanings defined in the disclosure, are used as flavouring agents or flavour enhancers in alimentary products. ... 08/18/05 - 20050182252 - Novel 2'-c-methyl nucleoside derivatives Compounds of Formula I, stereoisomers, and pharmaceutically acceptable salts or prodrugs thereof, their preparation, and their uses for the treatment of hepatitis C viral infection are described: ... ### FreshPatents.com Support |
