AMIDE DERIVATIVE, ITS PRODUCTION AND AGENT COMBATING PLANT DISEASES CONTAINING THE SAME AS ACTIVE INGREDIENT

摘要

NEW MATERIAL:An amide derivative of formula I (X is O, S). EXAMPLE:4-Methyl-5-oxazolylamino(2-furyl)acetonitrile. USE:It is used as an agent combating plant diseases. It can control radish downy mildew, apple late blight, cucumber gray late blight, potato late blight, or wheat brown snow blight. PREPARATION:The reaction of an oxazolylcarboxylic acid chloride of formula II with an aminoacetonitrile derivative of formula III is carried out preferably in the presence of a base such as pyridine at -30-50 deg.C, especially 0 deg.C to room temperature to give the compound of formula I.
