2-Phenyl-4-(3,4,5-trimethoxybenzylidene)-1,3-oxazol-5(4H)-one

Y.-F. Sun and Y.-P. Cui

Abstract: The title compound, C₁₉H₁₇NO₅, was synthesized as part of a continuing project involving the structures of oxazolone derivatives. The molecule adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is slightly twisted out of the plane of the oxazolone ring system by 11.2 (2)°. The crystal structure is stabilized by weak intermolecular C-HO hydrogen bonds.
