Selective reduction of double bonds in conjugated esters.
« on: April 24, 2017, 11:33:13 PM »
I was wondering if there are any reagents that can be used to selectively reduce a double bond in a conjugated ester (for instance: methyl-2-butenoate) .  If it is possible, could you also provide the mechanism?

I would guess just hydrogen gas and Pd/C catalyst. Mechanism is same as for any other double bond reduction by H2

If you dont want to use catalytic hydrogenation I think you can use a copperhydride reagent, I dont have any reference, sorry.

"This reagent was assigned as the "Reagent of the year" in 1991 for its functional group tolerance, high overall efficiency, and mild reaction conditions in the reduction reactions."
