title: Efficient and diverse synthesis of indole derivatives.
abstract: A convergent 2-step procedure toward an array of indole derivatives involving an Ugi reaction and a Pictet-Spengler reaction is described. The reactions are versatile regarding different starting materials. Hexacyclic 24 can be produced with unprecedented complexity.
