Abstract

A facile conversion of 2',3',5'-O-tri-(Bz, Tol or Ac)-N2-(Ac or iBu)-O6-DPC-guanosine to N2-(Ac or iBu)-guanosine has been achieved in 89-98% yield by short treatment with 90% aqueous TFA for smooth cleavage of the DPC group followed by treatment with sodium ethoxide in pyridine-ethanol mixture at room temperature.
