Synthesis of 3′-deoxy-3′-C-methyl-β-d-ribonucleoside analogs
摘要:
3'-Deoxy-3'-C-methyl-beta-D-ribonucleoside analogs bearing the five canonical bases of nucleic acids have been synthesized. All these derivatives were prepared by glycosylation of the corresponding heterocyclic bases with a suitable peracylated 3-C-methyl sugar precursor. The synthesis of the 3-C-methyl sugar precursor is described following a new stereoselective synthetic pathway. (C) 2007 Elsevier Ltd. All rights reserved.
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.
