Synthesis of acyclic nucleoside derivatives

Methods and novel intermediates for the preparation of acyclic nucleoside derivatives of the formula: where one of R1 and R2 is an amino acid acyl group and the other of R1 and R2 is a -C(O)C3-C21 saturated or monounsaturated, optionally substituted alkyl and R3 is OH or H; or a pharmaceutically acc...
