Simple steps, complex result: Consecutive organo‐catalyzed reactions of 3‐indolylmethanol compounds with aldehydes and N‐protected indoles lead to the formation of structurally complex cyclopenta[b]indoles (see scheme, Bn=benzyl). These one‐pot multistep reactions have a broad substrate scope and give the products in high yields, and with excellent diastereoselectivities and enantioselectivities.
简单的步骤,复杂的结果:3-吲哚基甲醇化合物与醛和N-保护的吲哚的连续有机催化反应会导致结构上复杂的环戊[ b ]吲哚的形成(参见方案,Bn =苄基)。这些一锅多步反应具有广泛的底物范围,可高收率地提供产物,并具有出色的非对映选择性和对映选择性。
