( Z )‐5–(Trideca‐4‐enyl)resorcinol (1) and gibbilimbols A—D (2–5) were synthesized in 47%‐60% yields over 6 steps from commercially available starting materials. The Wittig reaction of various alkyl phosphonium bromides with appropriate aldehydes in the presence of potassium ten‐butoxide ( t ‐BuOK) in anhydrous THF solution at room temperature served as the key step, and the result showed that only (Z)‐configuration olefins were formed by this procedure. The synthesis of the ( Z )‐5‐(trideca‐4‐enyl)resorcinol (1) was reported for the first time.
