Abstract: The title compound, C₁₉H₁₇NO₃S, crystallizes in the monoclinic space group P2₁/c, with four molecules in the unit cell. The structure contains a spiro-carbon connecting a bicyclo-octane group, consisting of two fused five-membered rings, to an acenaphthylene moiety. The five-membered ring containing the S atom is in an envelope conformation. The conformation of the other five-membered ring of the bicyclo-octane moiety is close to a half-chair. The methoxycarbonyl group is equatorially substituted.
