title: A novel approach to solid phase chemical synthesis of oligonucleotide mRNA cap analogs.
abstract: A novel approach for the synthesis of 5-capped 2'-O-methyloligoribonucleotides on a disulfide-tethered solid support is described. The key step of the synthesis is ZnCl2 promoted coupling of m7GDP imidazolide to a fully deprotected oligonucleotide 5'-phosphate on-support. By this methodology m7G5'pppm2'Apm2'Upm2'Ap has been prepared.
