An efficient method for the synthesis of (S)-7-aza-tryptophan via tridentate chiral auxiliary derived Ni(II)-complexes has been developed. This three-step synthesis includes alkylation, disassembling and Fmoc-protection. The desired Fmoc-L-7-AzaTrp-OH was obtained in over 49 % yield with excellent diastereoselectivity.
