An unambiguous synthesis of the (6R,7S)-diastereoisomer of asperlin from D-glucose involving a tandem epoxide formation/intramolecular Wadsworth–Emmons–Horner olefination has established the absolute configuration of the oxirane moiety in natural asperlin as (6S,7R). Keywords: asperlin, synthesis; Wadsworth–Emmons–Horner olefination; epoxide formation.
