Synthesis of antibiotics, puromycin and 3'-amino-3'-deoxy-N6,N6-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-alpha-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.
