5-Oxo-4-phenyl-1,2,3,4,5,7-hexahydrofuro[3,4-b]-2(1H)-pyridone

The six-membered ring in the title compound, C₁₃H₁₁NO₃, adopts a twist conformation and the lactone ring a planar conformation. The aryl group occupies a pseudo-axial position and is orthogonal to the plane through the pyridone ring. The molecules are linked by an intermolecular hydrogen bond between the N atom and the carbonyl-O atom of a neighbouring molecule [N1...O5(x, y − 1, z) = 2.820 (5) Å].
