I have a project where I have to expla
in a "fake" theoretical proposed mechanism reaction.
Using simple reagents how would I get from L-Glulonolactone to
3-Keto-L-glulonolactone? Please explain how the double bond would
form and the H would be removed. Please include a sketch with
curved arrows, and the name of the reaction used to make the single
bonded OH into a double bonded O.
Note: reaction does not have to be realistic or true.
Homework Answers
Here chromic acid is a
oxidising agent. It oxidise alcohol to ketone via removable of
hydrogen from oxygen which is in 3rd position of structure.
