Method for producing optically active cycloalkylidenebisoxazoline compound and intermediate thereof
Abstract:
It is provided to an optically active cycloalkylidenebisamidoalcohol compound represented by the formula (3): wherein R1 represents a C1-6 alkyl group, an optionally substituted phenyl group, an optionally substituted aralkyl group or a hydrogen atom, or two R1s, which are bonded to the same carbon atom, are bonded to form a ring together with the carbon atom to which they are bonded, R2 represents a C1-6 alkyl group, an optionally substituted aralkyl group or an optionally substituted phenyl group and * represents an asymmetric center, a method for producing it and a method for producing an optically active cycloalkylidenebisoxazoline compound represented by the formula (4): wherein R1, R2 and * are as defined above, using thereof.
