Preparation of an octadeoxyribonucleoside heptaphosphorothioate by the phosphotriester approach in solution

The synthesis of the octadeoxyribonucleoside heptaphosphorothioate, d[Tp(s)Tp(s)Gp(s)Gp(s)Gp(s)Gp(s)Tp(s)T] by the phosphotriester approach in solution is described. The phosphorothioate internucleotide linkages are protected by the S-(2-cyanoethyl) group
