Title (EN) PREPARATION OF PROPENOIC ACID DERIVATIVES
(FR) PREPARATION DE DERIVES D'ACIDE PROPENOIQUE
Abstract:
(EN) Compounds of formula (I), in which Ar is aryl and R1 and R2 are alkyl, are obtained by a process in which a compound of formula (II), where Z is a disubstituted amino group, is reacted (a) with an alcohol, R2OH, preferably under acidic conditions, to give a compound of formula (III), which is then dealkanolated, or (b) is hydrolysed under acid conditions, to give a compound of formula (IV), which is then alkylated. The compounds of formula (I) have fungicidal activity as do many of the compunds of formula (II), (III) and (IV).
(FR) Composé ayant pour formule (I), dans laquelle AR représente aryle et R1 et R2 sont des alkyles, obtenus par un procédé selon lequel un composé ayant pour formule (II), Z étant un groupe amino désubstitué, est mis en réaction (a) avec un alcool, R2OH, de préférence dans des conditions acides, afin d'obtenir un composé ayant pour formule (III), qui est ensuite désalcanolisé ou (b) est hydrolysé dans des conditions acides, pour donner un composé ayant la formule (IV), qui est ensuite alkylé. Les composés correspondant à la formule (I) ont une action fongicide, tout comme les composés correspondant aux formules (II), (III) et (IV).
