A practicalsynthesis 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 equivalent of β-MeTrp-OEt. The enantiomers were resolved via diastereomeric salt formation using a half equivalent of (R)-2-(4-hydroxyphenoxy)propionic
