Abstract

© 2020. The title compound, C26H20N2O5, is a rearrangement product of an o-pyridinyl anthracenyl isoxazole ester. It features a bicyclic acetal structure, which has two extended almost co-planar ring systems, which subtend a fold angle of 102.17(5)°. In the crystal, the molecules are closely knitted together through C - H⋯N and C - H⋯O hydrogen bonds and form chains of alternating enantiomers propagating along the c-axis direction.
