Abstract: In the title compound, C₂₃H₂₁NO₃S, the piperidine ring of the tetrahydroisoquinolinone unit adopts a screw-boat conformation. The thiophene ring is disordered in a 0.700 (3):0.300 (3) ratio by an approximate 180° rotation of the ring around the C-C bond linking the ring to the tetrahydroisoquinolinone unit. The benzene ring of the tetrahydroisoquinolinone unit makes dihedral angles of 83.1 (2) and 62.38 (11)° with the major occupancy thiophene ring and the phenyl ring, respectively. The dihedral angle between the phenyl ring and the thiophene ring is 71.0 (2)°. In the crystal structure, molecules are linked together by intermolecular C-HO and C-H interactions.
