Significance

In this paper, the authors explored a highly diversity-oriented strategy for the synthesis of tryptamines and homologues by combination of enantioselective allylation with a tandem hydroformylation-Fischer indole synthesis. Because stereocenters next to the olefinic bond are tolerated and do not epimerize, β-branched tryptamines were obtained with high enantiomeric purities.
