title: Solid-phase synthesis of deoxyribonucleotides having a cap structure analog.
abstract: In this study, the solid-phase synthesis of oligodeoxyribonucleotides having a guanosine pyrophosphate cap structure (Gpp-) was achieved by using a new guanosine monophosphate unit having the DMTr group capable of estimation of coupling efficiency of the pyrophosphate bond formation. Since 7-methylguanosine base was unstable under basic conditions, Gpp-capped DNA oligomers were synthesized by using a new linker having a silanediyl bond, which allowed to release the DNA chain from the solid support by treatment with fluoride anion under neutral conditions.
