Dynamic Kinetic Asymmetric Domino Oxa-Michael/Carbocyclization by Combination of Transition-Metal and Amine Catalysis: Catalytic Enantioselective Synthesis of Dihydrofurans
Into the pot: A one‐pot highly chemo‐ and enantioselectivecatalyticdomino oxa‐Michael/carbocyclization between α,β‐unsaturated aldehydes and propargylic alcohols is presented. This dynamickinetic transformation requires a combination of transition‐metal and aminecatalysis to afford functionalized dihydrofurans in good to high yields and up to 99.5:0.5 e.r.
