Abstract

In the title compound, C33H38N4O3, the mean planes of the 9H-xanthene unit and spiro­lactam (nine-atom) core are almost mutually perpendicular at 87.26 (6)°. Intra­molecular N—H⋯O and C—H⋯N inter­actions influence the 4-oxo­pent-2-en-2-yl­amino conformation. In the crystal, weak C—H⋯O hydrogen bonds link the mol­ecules into chains along [001].
