Derivatives of 3'-deoxythymidine (ddT) and 3'-deoxy-2',3'-didehydrothymidine (d4T) were prepared in which the 5'-hydroxyl group of the nucleoside was esterified to a bis-ketol phosphate. The resulting phosphate triesters are postulated to be prodrugs of the corresponding 5'-mononucleotides, which are formed intracellularly by the hydrolysis of the two ketol ester groups. The triesters were tested for
