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.

摘要:
Methods of deprotecting polynucleotides are disclosed. One aspect of the method of deprotecting polynucleotides, among others, includes: providing a polynucleotide, wherein the polynucleotide includes at least one nucleotide monomer that has at least one protecting group selected from the following: a base having a protecting group, a 2′-hydroxyl protecting group, and a combination thereof, and deprotecting at least one of the protecting groups of the polynucleotide by introducing the polynucleotide to a solution including an α-effect nucleophile.
