Efficient and Diverse Synthesis of Indole Derivatives
摘要:
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.
Polycyclic indole moieties are often part of bioactive natural or synthetic products, however traditionally have to be synthesized over several steps involving time consuming sequential multi-step syntheses. We herein communicate an efficient and flexible 2-step procedure to complex multicyclic indole alkaloid-type compounds involving Ugi MCR and Pictet-Spenglerreaction.
