Palladium(0)-catalyzed allylic alkylation of diketoester-dioxinones with allyl acetates under neutral conditions: Synthesis of hexasubstituted benzene derivatives

摘要

Intermolecular palladium(0)-catalyzed allylic alkylation of diketoester-dioxinones was performed under neutral conditions with 2-alkenyl and 2-cycloalkenyl acetates. Subsequent aromatization using cesium carbonate gave rise to isopropylidene-protected hexasubstituted resorcylates.
