Enantioconvergent Synthesis of Functionalized γ-Butyrolactones via (3 + 2)-Annulation
[Image: see text] A dynamic kinetic resolution of β-halo α-keto esters in an asymmetric homoenolate reaction is described. A chiral N-hetereocyclic carbene catalyzes the a(3) → d(3)-umpolung addition of α,β-enals to racemic α-keto esters, forming γ-butyrolactones with three contiguous stereocenters....
