Highly Enantioselective Bromocyclization of Tryptamines and Its Application in the Synthesis of (−)‐Chimonanthine

Abstract

Abkürzung: Eine enantioselektive Bromcyclisierung von Tryptamin unter Verwendung eines anionischen chiralen Phasentransferkatalysators führt direkt zu chiralen 3-Brompyrroloindolinen. Die Reaktion ermöglicht eine vierstufige enantioselektive Synthese von (−)-Chimonanthin. PG=Schutzgruppe.
