摘　　要：The title compound （C30H27NO3） was synthesized via a one-pot procedure starting from fl-benzoylthioacetanilide, benzaldehyde and 5,5-dimethyl-1,3-cyclohexanedione, and its structure was determined by single-crystal X-ray diffraction analysis. The crystal belongs to triclinic system, space group PI, with a = 6.325（2）, b = 11.243（3）, c = 17.553（4） A, a = 87.306（4）, β = 80.822（4）, γ = 77.798（4）°, V= 1204.2（5） A^3, Z = 2, Mr= 449.53, Dc= 1.240 g/cm^3, p = 0.080 mm^-1, F（000） = 476, the final R = 0.0459 and wR = 0.0970 for 2301 observed reflections with I 〉 2σ（I）.The title compound （C30H27NO3） was synthesized via a one-pot procedure starting from fl-benzoylthioacetanilide, benzaldehyde and 5,5-dimethyl-1,3-cyclohexanedione, and its structure was determined by single-crystal X-ray diffraction analysis.
