activation protocol has been developed for the synthesis of an 8-oxoprotoberberine core. It was successfully applied for the syntheses of (±)-8-oxocanadine, (±)-8-oxotetrahydropalmitine, and (±)-8-oxostylopine, which can be easily converted to the respective protoberberine natural products. The short synthetic route demonstrated would be useful for the synthesis of a large number of natural products and
已开发了一种Pd(II)催化的分子内串联烯烃酰胺化/ CH活化方案,用于合成8-氧代小ber碱核心。它已成功地用于合成(±)-8-氧卡西丁,(±)-8-氧四氢巴米汀和(±)-8-氧杂螺碱,它们可以轻松地转化为相应的原小ber碱天然产物。证明的短合成路线可用于合成大量天然产物和以小ber碱为原料的类似物。
