2-unsubstituted-1-methoxyindoles, based on our methodology for the synthesis of 1-methoxyindoles, is reported. This synthesis renders accessibility to a variety of natural products possessing the said skeleton. A direct synthesis of phytoalexin (1), (±)-paniculidine B (2), and (±)-paniculidine C (3) is disclosed based on the methodology. The synthesis of paniculidine B (2) has been achieved from aldehyde 10 in only two
据报道,基于我们合成1-甲氧基吲哚的方法,制备2-未取代的1-甲氧基吲哚的一般路线。该合成使具有所述骨架的多种天然产物可及。基于该方法公开了植物抗毒素(1),(±)-潘尼古丁B(2)和(±)-潘尼古丁C(3)的直接合成。潘尼古丁B(2)的合成仅由醛10分两步即可实现,产率为88%,而由使用我们较早方法获得的甲氧基吲哚化合物8分五步即可实现。
