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

A new approach for the construction of the hydrindane framework has been achieved by intramolecular 1, 6-conjugate addition under some basic conditions. The precursors, α, β, γ, δ-unsaturated esters (11a-11d) were synthesized from the ester 8 and acrolein derivatives (6a-6d) via aldol condensation. This methodology was applied to the total synthesis of (±)-coronafacic acid and its analogues.
