4-Benzyloxy-1-oxaspiro[4.6]undec-3-en-2-one

Abstract

The title compound, C17H20O3, the cycloheptane ring adopts a slightly distorted chair conformation. The planar five-membered ring is inclined at 57.13 (11)° to the phenyl ring of the benzyloxy substituent. In the crystal structure, C—H...O and C—H...π hydrogen bonds generate layers in the ac plane.
