Novel 4-Methylumbelliferone Amide Derivatives: Synthesis, Characterization and Pesticidal Activities.

A series of novel 4-methylumbelliferone amide derivatives were designed, synthesized and characterized by ¹H NMR, C NMR and HR-ESI-MS. The structures of compounds and (compounds named by authors) were further confirmed by X-ray single crystal diffraction. The acaricidal, herbicidal and antifungal activities of the synthesized compounds were assayed for their potential use as pesticide.
