Hello everyone!

I am trying to write out the mechanism for this reaction. My first step was to deprotonate Carbon 2 to create the double bond between 1 and 2 and remove the oxygen. Is this correct and how do I make the other double bond?

I don't remember much organic synthesis, I'm afraid. I can see how you will get an enol (or enolate, under alkaline conditions) but how do you think the oxygen is removed?

I realized I’ve made a mistake lol. I don’t know how to remove the oxygen. I’ll try to work on this later. Maybe it has something to do with a Michael addition?

What bothers me is that this looks like a reduction overall, yet I can't see what is being oxidised. Unless it is the methanol.
