While performing Stobbe reactions of a succinic diester derivative (1) different routes were found leading to different indole derivatives (2-5) depending on the reaction conditions applied, thus widening the scope and limitation of this useful procedure. Simpler pyrrolidine (13) and piperidine derivatives (14, 15) were also achieved through application of the intramolecular Stobbe reaction.
