The title compound, dinaphtho[2,1-b:2′,3′-d]furan-8,13-(8H, 13H)-dione, C20H10O3, was prepared in low yield from the reaction of (2-chloroethoxy)ethyl 2-tetrahydropyranyl ether with (R)-1,1′-binapth-2,2′-ol. The ring system is virtually planar [the largest deviation from the mean plane of the ring is 0.116 (4) A for atom C13] despite the O13...H1 short contact of 2.27 A.
