Abstract:
The present invention relates to the process of preparation of 2,3,4,9-tetrahydro-1/−/-β-carbolin-3-carboxylic acid esters substituted in position 1 of the general formula (I). in the preferred diastereoisomeric form through a single step starting from tryptophan in racemic form and/or its enantiomers and from 3,4-(methylenedioxy)benzaldehyde.
