Synthesis,Crystal Structure and Biological Evaluation of 4-Chloro-2-(morpholine-4-carbonyl)phenyl-4′-methoxybenzoate as Molluscicidal Agent

【摘要】：The title compound 4-chloro-2-(morpholine-4-carbonyl)phenyl-4'-methoxybenzoate(C19H18ClNO5, Mr = 375.79), a 5-chlorosalicylic acid derivative incorporating morpholine moiety, was conveniently synthesized through two steps and crystallized in the monoclinic space group P21/c with a = 7.8501(10), b = 9.3149(12), c = 25.133(3), V = 1836.2(4)3, Z = 4, Dc = 1.359 Mg/m3, λ = 0.71073, μ(MoKα) = 0.237 mm-1, F(000) = 784, R = 0.0447 and wR = 0.1227 for 3982 independent reflections with I 2σ(I). The dihedral angles formed between 4-methoxybenzene and 5-chlorobenzene rings, the 5-chlorobenzene and morpholine, and 4-methoxybenzene and morpholine rings are 82.55(3), 72.56(5) and 47.68(0)° by X-ray analysis, respectively. Bioassay shows that the title compound has a good molluscidal effect.
