Representatives of the C-homoaporphine class of alkaloids have shown interesting biological activities. To date the synthesis of these molecules has never been attempted via a direct-arylation strategy. We report herein the first Pd-mediated intramolecular direct arylation in the synthesis of C-homoaporphines via the use of microwaves. Use of tricyclohexylphosphine tetrafluoroborate as ligand gave
该代表Ç -homoaporphine类生物碱表明有趣的生物活性。迄今为止,从未尝试通过直接芳基化策略合成这些分子。我们在此报告了通过使用微波合成C-高吗啡的第一个 Pd 介导的分子内直接芳基化。使用三环己基膦四氟硼酸盐作为配体可提供良好的转化率并抑制与所评估底物的竞争性脱溴。这种芳基化策略应广泛用于合成C-高卟啉生物碱,如本文在 (±)-高红花碱的合成中所证明的。
