A method comprising an oximation step of reacting a formylalkenylcyclopropanecarboxylic acid ester represented by the formula (1):
(wherein, R
1
represents an alkyl group optionally having substituent(s) or halogen atom(s), and R
2
represents an alkyl group optionally having substituent(s) or a benzyl group optionally having substituent(s)) and hydroxylamine in a solvent in the presence at least one compound selected from the group consisting of carboxylic acids and carboxylic acid metal salts, to produce a hydroxyiminoalkenylcyclopropanecarboxylic acid ester represented by the formula (3):
(wherein, R
1
and R
2
are as defined above).
一种方法,包括以下步骤:在溶剂中,在至少选自羧酸和羧酸金属盐组成的群体中存在下,将式(1)所表示的甲醛烯丙基环丙烷羧酸酯(其中,R1代表一个具有取代基或卤素原子的烷基,R2代表一个具有取代基或一个具有取代基的苄基)和羟肟酸反应,从而生成式(3)所表示的羟肟基烯丙基环丙烷羧酸酯(其中,R1和R2如上所定义)。
