Palladium(0)-Catalyzed Allylic Alkylation of Diketoester–Dioxinones with Allyl Acetates under Neutral Conditions: Synthesis of Hexasubstituted Benzene Derivatives

Abstract

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
