Abstract
The invention relates to the chemical synthesis of oligonucleotides and to chemical entities useful in such synthesis. More particularly, the invention relates to sulfurization of the internucleotide linkages of oligonucleotides. The invention provides a process to synthesize new sulfur transfer reagents and a process for their use in sulfurizing oligonucleotides. The sulfur transfer reagents according to the invention are inexpensive to make, stable in storage and in solution, and highly efficient in sulfurization.
