SYNTHESIS OF OLIGONUCLEOTIDES

摘要

A method for the synthesis of a plurality of oligonucleotides in which an oligonucleotide is formed by sequential reactions of precursors of individual nucleotides on a support, comprising the steps of (a) forming a first oligonucleotide; (b) attaching to said first oligonucleotide a cleavable linker moiety; (c) forming a second oligonucleotide on the cleavable linker moiety; and (d) optionally cleaving the linker moiety to give the desired oligonucleotides. The invention also concerns nucleoside and non-nucleoside reagents suitable for incorporating cleavable linker moieties during automated oligonucleotide synthesis, cleavage of which produces oligonucleotides having a hydroxy or phosphate group at the 3' and 5' positions, and solid supports suitable for use in automated oligonucleotide synthesisers.
