A unified approach to four different (atisine, ajaconine, denudatine, and hetidine) diterpenoid alkaloid skeletons was developed and applied to the total synthesis of the natural products dihydroajaconine (2, atisine type) and gymnandine (4, denudatine type). The synthesis features a biogenetically inspired strategy that relies on C−H oxidation, aza‐pinacol coupling, and aza‐Prins cyclization as key
开发了一种统一的方法来处理四个不同的(atisine,ajaconine,denudatine和hetidine)二萜类生物碱骨架,并将其应用于天然产物dihydroajaconine (2,atisine型)和Gymnandine(4,denudatine型)的总合成中。该合成具有生物遗传学启发的策略,该策略依赖于CH氧化,氮杂频哪醇偶联和氮杂普林斯环化为关键步骤。
