<P>PROBLEM TO BE SOLVED: To solve the problem that, in conventional methods for producing an optically active cyclopropane compound, there are cases of being not always sufficiently satisfactory in terms of the selectivity of the compound's cis-trans isomers. <P>SOLUTION: An optically active bisoxazoline compound represented by formula (1) (wherein, R<SP POS="POST">1</SP>, R<SP POS="POST">2</SP>and R<SP POS="POST">3</SP>are each independently 1-8C alkyl, phenyl or benzyl; n is an integer of 0-3; and * denotes the asymmetric center) is provided. An asymmetric catalyst obtained by mixing the compound with a cuprous or cupric compound is also provided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
