Process for producing dioxolane nucleoside analogues |
| abstract |
The present invention relates to a process for preparing a dioxolane nucleoside analog of formula I or a pharmaceutically acceptable salt thereof, carried out in one reaction vessel, the process comprising a Lewis acid, a silylating agent. And adding a dioxolane of formula II to a non-silylated purine base or pyrimidine base or analog thereof. The present invention also provides a process for preparing a dioxolane compound of formula III by reacting a dioxolane compound of formula IV in a suitable solvent in the presence of DIB and I 2 using a suitable energy source. provide. |
