3-Cyano-6-(3-methoxyphenyl)-4-methylthio-2-pyranone

In the crystal structure of the title compound, C₁₄H₁₁NO₃S, the asymmetric unit consists of two molecules having different conformations. The main difference involves the orientation of the methoxy groups, but the angles between the two six-membered rings also differ slightly. This is the first reported structure of a δ-lactone with methylthio and cyano substituents.
