The intramolecular dimerization of unsymmetrical bis-1,2-(3-indolyl)ethanes could be controlled using either thermodynamic reaction conditions (neat trifluoroacetic acid) or kinetic conditions (2 equiv acid/chloroform). This control of regiochemistry has been applied to an efficient synthesis of (−)-tjipanazole F1.
