Guo, You-Yuan published the artcileSynthesis, crystal structure, and herbicidal activity of 3-(2-chloro-6-fluorophenyl)-4-(2-oxooxazolidine-3-carbonyl)-5-methylisoxazole, Computed Properties of 3919-74-2, the publication is Indian Journal of Heterocyclic Chemistry (2020), 30(4), 503-508, database is CAplus.
A novel N-aroyl diketone derivative, I (C14H10ClFN2O4, Mr = 324.69), was designed via fragment anal. and coupling strategy that led to highly potent and bio-selective herbicide. The title compound I was prepared by a multistep-reaction, including nucleophilic addition and N-acylation reaction using 2-chloro-6-fluorobenzaldehyde as the starting materials in 83.4% yield. The title compound I crystallized in the monoclinic system, space group P21/n with a = 10.7119(4) Å, b = 17.5875(7) Å, c = 11.5151(7) Å, β = 100.927(2)°, Z = 8, V = 2870.0(2) Å3, F(000) = 1328, Dc = 1.503 Mg/m3, crystal size: 0.130 x 0.120 x 0.100 mm. The herbicidal activity was tested against the gramineous weed Echinochloa crus-galli and broadleaf Abutilon juncea.
