Synthesis and NMR Characterization of Diastereomeric CPSMeG Derivatives
摘要:
Synthesis and stereochemical characterization of enantiomerically pure C(PSMe)G derivatives by NMR methods are reported. The effect of 5'-dimethoxytrityl on the conformational properties is described. It was found that in P-diastereomers the conformational differences about the C3'-O3' bond, as discernible from the Delta J values, are enhanced by the presence of this protecting group.
