near‐perfect Pd‐catalyzed kineticresolution of 1,3‐disubstituted unsymmetrical allylic acetates uses silyl enol ethers as nucleophiles to access the important 3‐substituted‐furanone scaffold (see scheme; DACH=diaminocyclohexyl, dba=dibenzylideneacetone). The reaction proceeds under mild conditions and provides the desired products with excellent chemo‐, regio‐, and enantioselectivity.
