Q. Liu, R. Qu and J. Xu

Abstract: The title compound, C₂₂H₁₇NO₃, is one of the photoreaction products of N-methyl-1,8-naphthalenedicarboximide with 4-methoxyphenylacetylene. The planar cyclobutene ring makes a dihedral angle of 70.36  (8)° with the benzene ring of the tetralin moiety. The substituted phenyl ring is twisted by 21.15  (14)° with respect to the attached cyclobutene ring.
