8'-Methoxy-3H-spiro[1-naphthofuran-2,2'-chroman]

G. R. Clark, K. Y. Tsang and M. A. Brimble

Abstract: The crystal structure of the title compound, C₂₁H₁₈O₃, has been determined to establish the relative stereochemistry at the spiro ring junction. Each O atom adjacent to the junction lies axial to the neighbouring ring; this is presumably due to anomeric effects.
