Product-specific evaluation notes
Potential advantages
- 3′-O-methylation provides a defined blocked ribose terminus and is analytically distinguishable from the corresponding 2′-O-methyl isomer.
Method limitations
- The 3′-O-methyl group blocks normal 3′-hydroxyl extension; confirm that this behavior matches the intended enzyme or synthesis workflow.
