N-(dimethylsulfamoyl)-protected aldimines with a number of allyl bromides followed by high-yielding deprotection afforded allylic amines in good to excellent yields. The racemic amines were then subjected to enzymatic kinetic resolution in order to obtain the corresponding (S)-amines and (R)-amides. When acyl donors with a terminal double bond were applied in the enzymatic kinetic resolution, the product amide
