Synthesis and Antifungal Bioactivity of Methyl 2‐Methoxyimino‐ 2‐{2‐[(substituted benzylidene)aminooxymethyl]phenyl}acetate and 2‐Methoxyimino‐2‐{2‐[(substituted benzylidene)aminooxy‐ methyl]phenyl}‐N‐methylacetamide Derivatives

Abstract Ten methyl 2‐methoxyimino‐2‐{2‐[(substituted benzylidene)aminooxymethyl]phenyl}acetate and 2‐methoxy‐ imino‐2‐{2‐[(substituted benzylidene)aminooxymethyl]phenyl}‐ N ‐methylacetamide derivatives were synthesized. Structures of the new compounds were characterized by IR, 1 H NMR and GC‐MS data. These compounds at 10 µg/mL were tested in vitro against five pathogenic fungi, namely, Sclerotonia, Botrytis cinerea Pers, Gibberella zeae , Rhizoctorua solani and Pyricularia oryzae . Compounds G 5 , G 6 , G 7 and G 8 showed potent antifungal activities against Botrytis cinerea Pers , G 7 against Gibberella zeae and G 7 , G 8 against Rhizoctorua solani , respectively.
