An N-Substituted 6,7-Benzocoumarin-8,9-aziridine Derivative

In the title compound, 8-(2-bromo-4-methylphenyl)-4-methyl-2,7,7a,8,8a,9- hexahydropyrano[2′,3′:1,2]naphth[6,7]aziridin-2-one, C₂₁H₁₈BrNO₂, the tetrahydrobenzene ring adopts a flattened boat conformation. The aziridine plane forms dihedral angles of 80.4 (1) and 59.1 (2)° with the tetrahydrobenzene ring plane and the N-phenyl substituent ring plane, respectively. The crystal structure is stabilized by weak C-H...O intermolecular hydrogen bonds and π-π stacking interactions of the coumarin ring.
