Synthesis and in vitro Fungicidal Activity of a Series of Novel N‐(Heterocycly)phthalimides

A series of novel phthalimides was prepared and tested for antifungal activity in vitro against seven phytopathogenic fungi:Rhizoctonia solani, Fusarium oxysporum f.sp. cucumerinum Owen., Botrytis cinerea, Fulvia fulva, Sclerotinia sclerotiorum de Bary, Phytophthora capsici, Botryosphaeria berengeriama. The results showed that those compounds holding the structure of 6-methylpyridin-2-yl exhibited good activity against Phytophthora capsici and Botrytis cinerea.
