A synthetic shortcut: A highly efficient cascade reaction (see scheme) led to polycyclic indoles with excellent enantioselectivity. The combination of the two steps through sequential catalysis enables the use of more readily available starting materials and makes the synthesis more practical. Boc=tert‐butoxycarbonyl.
合成捷径:高效的级联反应(请参见方案)导致对映体选择性优异的多环
吲哚。通过顺序催化的两个步骤的组合使得能够使用更容易获得的起始原料并使合成更实用。Boc =叔丁氧羰基。
