Abstract

Three critical advances in simplifying the adoption of P(V)-based stereopure, phosphorothioate-containing oligonucleotide synthesis are reported. A more inexpensive phosphorus-sulfur incorporation reagent (Ψ^Br) is introduced, a robust linker system was developed, and a systematic study of common nucleobase protecting groups was performed to significantly reduce the barrier to adoption of this technology.
