Tryptamine and 3-methylbut-2-enal furnished the conjugated imine 3b which cyclised with pyridine-tosyl chloride to yield the N-tosyl-tetrahydro-β-carboline 10; alternatively in pH 6.2 aqueous buffer the hydroxyisobutyl derivative 9b was formed.The reaction of L-tryptophan methyl ester with the same aldehyde and the possible biosynthetic relevance of these studies are discussed.
