3-[(E)-1-(Benzyloxyimino)ethyl]-7-(3-methylbut-2-enyloxy)-2H-chromen-2-one

Abstract

In the title compound, C23H23NO4, the dihedral angle beween the chromen-2-one ring system and the benzene ring is 69.73 (10)° and the molecule adopts an E conformation with respect to the C=N double bond. In the crystal, inversion dimers linked by pairs of C—H...O hydrogen bonds occur, generating R22(12) loops.
