N2  - Enamine methyl esters are obtained by methylation of the condensation product from a 1,3-dicarbonyl compound with L-tryptophan, or directly from methyl L-tryptophanate and the 1,3-dicarbonyl compound. Protonation of these enamines forms either methyl L-tryptophanate or a tetrahydro-&#946;-carboline derivative (two diastereomers in certain cases), depending on the structure of the dicarbonyl compound. Enamines from 1,3-dicarbonyl compounds and tryptamine yield similar cyclic products on protonation.
