METHOD AND COMPOSITIONS FOR THE SYNTHESIS OF DIOXOLANE NUCLEOSIDES WITH .BETA.-CONFIGURATION |
| 摘要 |
<p>The present invention relates to methods and compositions for preparing biologically important nucleoside analogues containing 1,3-dioxolane sugar rings. In particular, this invention relates to the stereoselective synthesi s of the beta (cis) isomer by glycosylating the base with an intermediate of formula (II) below a temperature of about -10 ~C, wherein R1 and L are as defined herein.</p> |
