    Abstract: 2,3-Dialkoxy-4-pyridinol derivatives of formula (I) are new. In (I), R1,R2, R3=C1-3 lower alkyl; R4= arylalkyl, alkylarylalkyl, alkoxyarylalkyl, aryloxyalkyl which may be substd. hydroxy and (or) thiol. Cpd. (I) were prepd by the reaction of comp. (II) with compd. R4X in the presence of anhydrous polar solvent (e.g., tetrahydrofuran, dimethyl formamide, hexamethyl phostriamide) at room temp. The compd. (II) was also prepd., where R1,R2,R3 are methyl groups. Cpd. (I) has insecticidal activity.

    Abstract translation: 式(I)的2,3-二烷氧基-4-吡啶酚衍生物是新的。 在(I)中,R 1,R 2,R 3 = C 1-3低级烷基; R 4 =芳基烷基,烷基芳基烷基,烷氧基芳基烷基,可被取代的芳氧基烷基。 羟基和(或)硫醇。 CPD。 (I)通过化合物的反应制备。 (二)与compd。 R4X在室温下在无水极性溶剂(例如四氢呋喃,二甲基甲酰胺,六甲基磷酰三胺)存在下进行。 compd。 (II)也是制备的,其中R1,R2,R3是甲基。 CPD。 (I)具有杀虫活性。
