Ni(II)-complexes, derived from glycine Schiff bases with chiral tridentate ligands, have been used as powerful tools for the synthesis of structurally diverse tailor-made amino acids. In this manuscript, asymmetric alkylation reaction between chiral nucleophilic glycine derived Ni-complex and 3-(chloromethyl)-1H-pyrrolo[2,3-b]pyridine has been developed under convenient conditions, which affords the corresponding alkylated Ni-complex in 74 % yield and excellent diastereoselectivity (only one isomer). This reaction features convenient conditions and completely controlled diastereoselectivity, which provides a highly valuable approach for asymmetric synthesis of 7-aza-tryptophan.

The synthesis of (-)-(R)-7-azatryptophan (2) from commercially available 7-azaindole (4) is described.The key step involved the diastereoselective alkylation of tert-butyl acetate (3) with 1-(tert-butyloxycarbonyl-3-(iodomethyl)-7-azaindole (14).The alkylation, conducted at -100 deg C in a THF/HMPA solvent using potassium hexamethyldisilazide as the base, afforded 7 in a greater than 98 percent diastereomeric excess.Hydrolysis and deprotecting gave (-)-(R)-7-azatryptophan.
