Lanthionines, thioether-linked alanines, are readily available from differentlyprotected β-bromoalanine and cysteine derivatives under phase-transfer conditions at pH 8.5. Racemisation or elimination of starting materials or products was not observed. Also base-sensitive protecting groups, such as, for instance, the Fmoc group, were compatible with this procedure, thus conveniently permitting the
