Abstract

The title compound, C15H20O3, was obtained from Angelica polymorpha and shows antifeedant activity. The penta‐1,3‐diene fragment is essentially planar and the planarity extends to the adjacent C and O atoms of the benzofuran system. The six‐membered ring of this system adopts a distorted chair conformation. The penta‐1,3‐diene fragment is essentially planar and the planarity extends to the adjacent C and O atoms of the benzofuran system. In the crystal structure, intermolecular O—H...O hydrogen bonds form zigzag rows along b and weak C—H...O interactions further stabilize the structure.
