Hi, this reaction is reversible and I have the mechanism for the 6-membered ring converting into its furanose form with a 5-membered ring. Could you please provide the reverse reaction arrow-pushing mechanism where the 5-membered furanose ring is converted to its pyranose 6-membered ring form?
Thank you very much!
