Synthesis of antibiotics, puromycin and 3 ′-amino-3 ′-deoxy-N 6 ,N 6 -dimethyladenosine 11 was achieved by utilizing the cyclic sulfite 6a of the xylo -3 ′,5 ′-dihydroxy group as a new protective group. The key synthetic step is the deprotection of the sulfite moiety through the intramolecular cyclization of 2-α-carbamate 7 . In a similar manner, 2,2 ′-anhydro-pyrimidine nucleosides 15 , ribo -cytidines 17 and 2 ′,3 ′-anhydroadenosine 14 were prepared in high yields from the corresponding sulfites 4 , 5 , and 6b , respectively.
