Oxyanion-steering and CH-π Interactions as Key Elements in a N-Heterocyclic Carbene-Catalyzed [4+2] Cycloaddition

The N-heterocyclic carbene catalyzed [4+2] cycloaddition has been shown to give γ,δ-unsaturated δ-lactones in excellent enantio- and diastereoselectivity. However, preliminary computational studies of the geometry of the intermediate enolate rendered ambiguous both the origins of selectivity and the...
