Crystal structure of (3S*,4R*)-4-fluoro-3-(4-meth­oxy­phen­yl)-1-oxo-2-phenyl-1,2,3,4-tetra­hydro­iso­quinoline-4-carb­oxy­lic acid

The title compound, C(23)H(18)FNO(4), crystallized as a racemate. It exhibits a cis conformation with respect to the F atom and the methine H atom. The piperidine ring has a screw-boat conformation. The meth­oxy­phenyl ring and the phenyl ring are inclined to the mean plane of the iso­quinoline ring system by 89.85 (4) and 46.62 (5)°, respectively, and by 78.15 (5)° to one another. In the crystal, mol­ecules are linked by an O—H⋯O hydrogen bond forming chains propagating along the a-axis direction. The chains are linked by C—H⋯F hydrogen bonds, forming layers lying parallel to the ab plane.
