Synthesis of 2',3'-dideoxyinosine via radical deoxygenation.
A synthetic method for 2',3'-dideoxyinosine (ddI) from inosine was established via radical deoxygenation of N1,5'-O-diprotected-2',3'-bis-S-methyl dithiocarbonate of inosine derivatives. The radical deoxygenation proceeded smoothly to give the desired dideoxy compounds in good yields using 1-ethylpiperidinium hypophosphite and triethylborane. Benzyl or p-methoxybenzyl protection of inosine at the N1, 5'-O-positions were effective for the ddI synthesis.
