Chemical synthesis of the 5'-terminal structure of U1 RNA
Nucleic Acids Symposium Series
|January 1, 1990
Abstract:
A new method for the synthesis of N2,N2-dimethylguanosine (DMG) is developed by reductive C-S bond cleavage by use of tributyltin hydride. An improved method for the synthesis of the key intermediate (1) for construction of the 5'-terminal structure of U1 RNA, which has a trimethylated cap (TMG) structure at its 5' end, is also described. By the use of 1, several TMG-capped ribonucleosides and oligonucleotides were synthesized.
