OPTICALLY ACTIVE BISOXAZOLINE COMPOUNDS, PROCESS FOR PRODUCTION OF THE SAME AND USE THEREOF

摘要

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 C1-6 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 C1-6 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.
