Abstract
NEW MATERIAL:A thiophene derivative shown by the formulaI(X is H, alkyl metal atom, lower alkylcarbonyl, lower alkoxy lower alkylcarbonyl, lower alkylthio lower alkylcarbonyl, halogen-substituted lower alkylcarbonyl, cycloalkylcarbonyl, etc.; R is lower alkyl).
EXAMPLE: 3,4-Dihydroxy-2-cyano-5-carbethoxy-thiophene.
USE: An agricultural and gardening fungicide. Exhibiting a controlling effect on blast of rice plant, helminthosporium leaf spot of rice plant, late blight of tomato, stem rot of a kidney bean, etc.
PROCESS: As shown by the reaction formula, for example, ethyl oxalate is reacted with ethyl ester of cyanomethyl thioglycol and sodium ethylate, to give precipitated sodium salt, which is subjected to acid precipitation with hydrochloric acid. A compound shown by the formulaIis obtained by recrystallization of the resulted compound with acetic acid.
