Abstract
There is provided a method for producing a cyclopropanecarboxylate of formula (3): wherein R1, R2, R3, R4 and R5 each independently represent: a hydrogen atom, halogen atom, an optionally substituted alkyl group and the like; and R7 represents: an optionally substituted alkyl group, and the like, which is characterized by reacting a cyclopropanecarboxylate of the formula (1) wherein R1, R2, R3, R4 and R5 are as defined above, and R6 represents an alkyl group having 1 to 10 carbon atoms or an optionally substituted phenyl group, with a monohydroxy compound of the formula (2): R7OH (2) wherein R7 is the same as defined above, in the presence of an alkali metal hydroxide.
Claims9
A method for producing cyclopropanecarboxylate of the formula (3):
- wherein R1, R2, R3, R4 and R5 each independently represent:
- a hydrogen atom, a halogen atom,
- an optionally substituted alkyl group,
- an optionally substituted alkenyl group,
- an optionally substituted aralkyl group or
- an optionally substituted aryl group;
- and
- R7 represents:
- an optionally substituted alkyl group,
- an optionally substituted aralkyl group, or
- an optionally substituted aryl group,
- which comprises:
- reacting a cyclopropanecarboxylate of the formula (1)
- wherein R1, R2, R3, R4 and R5 are as defined above, and
- R6represents an alkyl group having 1 to 10 carbon atoms or an optionally substituted phenyl group,
- with a monohydroxy compound of the formula (2):
- R7OH (2)
- wherein R7 is the same as defined above, in the presence of an alkali metal hydroxide that is LiOH or LiOH.H2O.
