Such methods find use in synthesis of polynucleotides. The method involves contacting a functionalized support with a precursor having an exocyclic amine triaryl methyl protecting group under conditions and for a time sufficient to result in internucleotide bond formation. The functionalized support includes a solid support, a triaryl methyl linker group, and a nucleoside moiety having a reactive site hydroxyl, the nucleoside moiety attached to the solid support via the triaryl methyl linker group. In particular embodiments, the precursor has the structure: n nwherein:n O and H represent oxygen and hydrogen, respectively R1 is hydrido, hydroxyl, protected hydroxyl, lower alkyl, modified lower alkyl, or alkoxy, one of R2 or R3 is a hydroxyl protecting group; and the other of R2 or R3 is a reactive group capable of reacting with the reactive site hydroxyl, Base is a heterocyclic base having an exocyclic amine group, and Tram is the exocyclic amine triaryl methyl protecting group.
专利号:US-7576245-B2 优先权日:2002-07-11 标题:Fluorous tagging and scavenging reactants and methods of synthesis and use thereof 发明人:ZHANG WEI; LUO ZHIYONG 权利人:FLUOROUS TECHNOLOGIES INC 摘要:The present invention includes methods and compositions for increasing the fluorous nature of an organic compound by reacting it with at least one fluorous compound to produce a fluorous tagged organic compound. The increased fluorous nature of the fluorous tagged organic compound can then be utilized to separate the fluorous organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom. The resultant fluorous tagged organic compound can be subjected to subsequent chemical transformations, wherein the fluorous nature of the tagged compound is utilized to increase the ease of separation of the fluorous tagged organic compound from untagged reagents, reactants, catalysts and/or products derived therefrom, after each chemical transformation. The chemical transformations result in a second fluorous tagged organic compound wherein the fluorous nature of the second fluorous tagged organic compound can then be reduced by removing the fluorous group therefrom, thereby producing a second organic compound that may be employed as a pharmaceutical compound or intermediate, or a combinatorial library component.
