✦ Synopsis

The title compound, C 15 H 20 O 3 , was obtained from Angelica polymorpha and shows antifeedant activity. The penta-1,3diene 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-HÁ Á ÁO hydrogen bonds form zigzag rows along b and weak C-HÁ Á ÁO interactions further stabilize the structure.
