A practical synthesis of enantiopure β-methyltryptophan ethyl ester for a preparation of diabetes drug

A practical synthesis of (2R,3S)- and (2S,3R)-β-methyltryptophan ethyl ester (β-MeTrp-OEt) has been developed. Racemic threo-β-MeTrp-OEt was diastereoselectively prepared via crystallization-induced diastereomer transformation (CIDT) of the α-nitro equiva
