increase the oral bioavailability of the anti-HIV agent 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA; 1). The majority of the bis(alkyl ester) and bis(alkyl amide) prodrugs were prepared by alcohol or amine displacement of dichlorophosphonate 2. Basic hydrolysis of the bis(esters) or bis(amides) provided the corresponding monoesters or monoamides. Synthesis of bis[(acyloxy)alkyl] phosphonates 10a-c was accomplished
