Optically active bisoxazoline compounds represented by the general formula (1), a process for producing the compounds, and a process for producing cyclopropanecarboxylic esters by using the same:
wherein R
1
and R
2
are the same and each represents C
1-6
alkyl, substituted or unsubstituted aralkyl, or substituted or unsubstituted phenyl or R
1
and R
2
are bonded each other together with the carbon atom of oxazoline ring to which they are bonded to form a ring; R
3
is substituted or unsubstituted naphthyl; R
4
and R
5
are the same and each represent hydrogen or C
1-6
alkyl, or R
4
and R
5
are bonded each other together with the carbon atom to which they are bonded to form a cycloalkyl ring having 3 to 6 carbon atoms; and * represents an asymmetric center.
