The synthesis of some 3'-deoxy-3'-C-methylnucleoside analogues bearing naturally occuring nucleic acid bases was achieved from the preparation of a suitable peracylated 3-deoxy-3-C-methyl sugar using a stereoselective pathway. In addition, examples of chemical modifications at the 2' position are presented.
Synthesis of 3′-deoxy-3′-C-methyl nucleoside derivatives
2',3'-Dideoxy-3'-C-methyl nucleosides bearing the five naturallyoccurring nucleic acid bases were synthesized. Additionally, the 3'-deoxy-3'-C-methyl nucleoside analogues bearing 5-aminoimidazole-4-carboxamide as well as 1,2,4-triazole-3-carboxamide moieties were prepared. The synthesis of the corresponding 2',3'-dideoxy-3'-C-methyl triazole derivative was also accomplished. The dideoxynucleoside
