Studies toward Oxyacetamide-Linked RNA Analogues: Synthesis and Conformation of a Modified Dinucleoside
摘要:
A new oxyacetamide-modified dinucleoside with 5'-(S) chirality, a hydrophobic 5'-C-(2-methoxyethyl) group, and a 2'-O-methyl group was synthesized from D-glucose. This dinucleoside showed a helical structure based on CD and NMR spectroscopy. The sugar puckering at the 5' and 3' ends were found to be 'S'- and 'N'-types, respectively. These results were substantiated by ab initio density functional theory.
