[reaction: see text] Both unsaturated proline derivatives and opticallyactivetryptophan analogues have been obtained via Pd-catalyzed cyclization of aniline-containing acetylenic amino acids. The side chain length of the cyclization precursor determines which one of the two possible products will be formed.
