A new method was developed for the one-pot synthesis of substituted 3-(2-aminoethyl)- and 3-(3-aminopropyl)indoles from commercially available aryl hydrazines and chloroalkylalkynes. Various tryptamine derivatives were prepared directly in good yield with excellent regioselectivity. The method involves a new domino reaction sequence consisting of a titanium-catalyzed amination of the chloroalkylalkyne, [3+3]-rearrangement of the resulting aryl hydrazone, and nucleophilic substitution of the chloride by ammonia.

Reaction of tosylmethyl isocyanide with substituted formyl indoles gave the nitrile with one more carbon atom.Hydrogenation of this nitrile afforded the corresponding tryptamine.
