Modified sodium borohydrides were used in the reduction of the imine moiety in compounds containing the (R)-1-arylethylamine motif as a chiral auxiliary. Diastereomeric products were formed with moderate to good stereoselectivity and were effectively separated by column chromatography.Key words: asymmetric synthesis, indole alkaloids, hydrogen bond.
