                                    Coronafacic acid (1) is an acid component of coronatine, and has been isolated from several pathovars of Pseudomonas syringae. Syntheses of C6-non- and C6-alkyl-substituted analogues of 1 were accomplished via intramolecular 1,6-conjugate addition as the key step. Among them, 1 and four C6-alkyl-substituted analogues exhibited potato tuber-inducing activity, but the C6-non-substituted analogue did not
