2-Phenyl-4-(3,4,5-trimethoxy-benzyl-idene)-1,3-oxazol-5(4H)-one

Abstract

The title compound, C19H17NO5, was synthesized as part of a continuing project involving the structures of oxazolone derivatives. The mol-ecule 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 inter-molecular C - H⋯O hydrogen bonds.
