    摘要: The invention provides methods for synthesizing oligonucleotides using nucleoside monomers having carbonate protected hydroxyl groups that are deprotected with α-effect nucleophiles. The α-effect nucleophile irreversibly cleave the carbonate protecting groups while simultaneously oxidizing the internucleotide phosphite triester linkage to a phosphodiester linkage. The procedure may be carried out in aqueous solution at neutral to mildly basic pH. The method eliminates the need for separate deprotection and oxidation steps, and, since the use of acid to remove protecting groups is unnecessary, acid-induced depurination is avoided. Fluorescent or other readily detectable carbonate protecting groups can be used, enabling monitoring of individual reaction steps during oligonucleotide synthesis. The invention is particularly useful in the highly parallel, microscale synthesis of oligonucleotides.

    摘要: Functionalized supports for polynucleotide synthesis are disclosed. The supports have linker moieties that are stable to conditions used in polynucleotide synthesis, but may be cleaved to release synthesized polynucleotides from the support. Methods of making the functionalized supports and methods of using are also disclosed.

    摘要: Methods of forming an internucleotide bond are disclosed. 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.
