PROCESS FOR PRODUCTION OF CYCLOPROPANECARBOXYLIC ACID ESTER COMPOUND

摘要

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.).
