synthetic method for 5′-deoxy-5′-thioguanosine-5′-monophosphorothioate by combining two known reactions and measured its incorporation efficiency into the 5′-terminus of RNA by in vitro transcription using T7 RNA polymerase that requires guanosine to efficiently initiate transcription, followed by treatment of alkaline phosphatase, yielding a terminal sulfhydryl group at the 5′-termini of RNA molecules.

[figure: see text] 5'-Deoxy-5'-thioguanosine-5'-monophosphorothioate (GSMP) was synthesized in four steps with 35% overall yield. GSMP serves as a good substrate for in vitro transcription with T7 RNA polymerase to yield 5'-GSMP-RNA, which was converted to 5'-HS-RNA by dephosphorylation with alkaline phosphatase. The thiol-reactive agents can be efficiently introduced into the 5'-terminus of RNA.
