Abstract
In order to search for novel fungicides with high activity, a series of 2-h eteroaryl-4-chromanones were designed and synthesized via bioisosterism sub stitution. The structures of all new compounds were confirmed by spectrosco pic methods and microanalyses. Preliminary bioassays indicated that some co mpounds showed fungicidal activity against Rhizoctonia solani, Fusarium oxy sporum, Physalospora piricola and Cercospora beticola.
