catalyzed tandem alcohol amination/Pictet–Spengler reaction sequence to synthesize tetrahydro-β-carbolines from an alcohol and tryptamine. Our conditions use a Lewis acid cocatalyst, In(OTf)3, that is compatible with typically base catalyzed amination and an acid catalyzed Pictet–Spengler cyclization. This method proceeds well with benzylicalcohols, heterocyclic carbinols, and aliphatic alcohols. We also
