An efficient and practical asymmetric synthesis of erythro-(1R,2S)-8-O- 4′-neolignan myrislignan was achieved by using vanillin and pyrogallic acid as the starting materials. Two key steps are involved: preparation of an enantiopure threo alcohol of predictable stereochemistry by dihydroxylation with AD-mix-β, and inversion of the absolute configuration from the threo to the erythro isomer using a Mitsunobu reaction. The route illustrates a new methodology for the synthesis of erythro-8-O-4′-neolignan. Graphical abstract: [Figure not available: see fulltext.]
