Jh. Boal et al., THE 5'-HYDROGEN PHOSPHONATE ANALOG AS A POTENTIAL PRODRUG OF 3'-AZIDO-2',3'-DIDEOXYTHYMIDINE (AZT), Nucleosides & nucleotides, 12(10), 1993, pp. 1075-1084
A novel synthesis of AZT-5'-H-phosphonate 2, involving decarboxylation
of the phosphonoformate intermediate 7, is reported herein. Studies o
f the metabolism of 2 in U937 cells indicate that 2 is readily convert
ed to AZT-5'-monophosphate.
