Twice as good: The title reaction using the tryptophan‐derived bifunctional organic catalyst 1 has been developed. The reported method led to the synthesis of chiral γ‐substituted butenolides in excellent yields, with high diastereo‐ and enantioselectivities. Facile synthesis of chiralglycerolderivatives containing a tertiary hydroxy group has also been demonstrated.
