title: Solid phase synthesis of U1 RNA oligomers containing a TMG cap structure.
abstract: We report the solid-phase synthesis of a 5'-terminal part of U1 RNA. In this approach, a new method for pyro- and tri-phosphate bond formation on solid supports was studied. Since 2,2,7-trimethyl guanosine (TMG) in the cap structure was unstable under basic conditions, a RNA oligomer was synthesized by using a linker having the P-N bond, which can be cleaved from the solid support by treatment with 80% acetic acid.
