title: X-ray investigations of bicyclic alpha-methylene-delta-valerolactones. III. trans-(4aR,8aR)-4a-Methoxy-3-methyleneperhydrochromen-2-one.
abstract: The title compound, C11H16O3, adopts a conformation in which the delta-valerolactone and cyclohexane rings are almost coplanar with one another. The beta-methoxy substituent occupies an axial position with respect to the cyclohexane ring. The delta-valerolactone moiety adopts a half-chair arrangement, while the cyclohexane ring exists in a chair conformation.
