Abstract: The molecular structure of the title compound, C₂₀H₁₉NO₃, contains a spiro-C atom connecting a bicyclooctane group, consisting of two fused five-membered rings, to an acenaphthylene moiety. One of the five-membered rings of the bicyclooctane moiety is in an envelope conformation, while the conformation of the other five-membered ring is close to a half-chair. The methoxycarbonyl substituent is equatorial.
