Erythro-D,L- and threo-D,L-beta-methylphenylalanine, -beta-methyltyrosine and -beta-methyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid were synthesized. High-performance liquid chromatographic methods were developed for the separation and identification of the enantiomers of the beta-methyl amino acids, with the application of 1-fluoro-2,4-dinitrophenyl-5-L-alanine amide and 2,3,4,6-tetra-O-acetyl-beta-D-glucopyranosyl isothiocyanate as derivatizing reagents.

The in vitro pharmacological properties and conformational features of analogs of the delta opioid receptor selective tetrapeptide Tyr-c[D-Cys-Phe-D-Pen]OH (JOM-13) in which the Phe3 residue was replaced by each of the four stereoisomers of beta-methylphenylalanine (beta-MePhe) were investigated. Both analogs in

A reversed-phase high-performance liquid chromatographic (RP-HPLC) method was developed to obtain pure erythro[2S3S, 2R3R]- and threo[2S3R, 2R3S]-beta-methylphenylalanine. These amino acids were incorporated into an enkephalin, H-Tyr-D-Ala-Gly-beta-MePhe-Val-Val-Gly-NH2, and into a deltorphin C, H-Tyr-D-Ala-beta-MePhe-Asp-Val-Val-Gly-NH2, analogue, which yielded four diastereoisomers of the peptides.

A direct preparative purification of all four isomers of the unnatural amino acid beta-methylphenylalanine was achieved using supercritical fluid chromatography (SFC) with stacked-injection. Final purification of the Cbz-methyl ester derived isomers was performed on a Daicel Chiralpak AD-H column (20
