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.
分子间钯(0)催化的二酮基酯-二恶英酮的烯丙基烷基化反应是在中性条件下,使用乙酸2-烯基酯和2-环烯基乙酸酯进行的。随后使用碳酸铯的芳构化产生了异亚丙基保护的六取代的间苯二酸酯。
