Ds. Kemp et Ec. Young, PROGRESS TOWARD A NOVEL C-TERMINAL HELIX CAPPING PRINCIPLE - SYNTHESIS AND PROPERTIES OF (S)-ALPHA-(2-AMINOETHYL)-METHIONINE, Tetrahedron letters, 35(45), 1994, pp. 8315-8318
(S)-alpha-(2-aminoethyl)-methionine 9 ((s)-2,4-diamino-2-(3-thiabutyl)
-butanoic acid) is synthesized in three steps from yl-2-tert-btuyl-5-(
3-thiabutryl)-oxazolidin-4-one. Neighboring group reactions of peptide
derivatives of 9 are described.
