OPTICALLY ACTIVE AMINO ACID DERIVATIVE HAVING AXIAL ASYMMETRY, AND METHOD FOR PRODUCING OPTICALLY ACTIVE COMPOUND USING THE AMINO ACID DERIVATIVE AS ASYMMETRIC CATALYST

摘要

PPROBLEM TO BE SOLVED: To provide an advantageous method for producing an optically active compound useful as a synthetic intermediate of a medicine or the like by developing a new nonmetallic asymmetric catalyst capable of achieving high-yield and highly stereoselective asymmetric reaction. PSOLUTION: The amino acid derivative is represented by general formula (I) [wherein, RSP1/SPis an aryl group which may have a substituent, a group represented by the formula: -COSB2/SBRSP4/SP(wherein, RSP4/SPis a hydrogen atom or the like) or the like; and RSP2/SPand RSP3/SPare the same or different and each a hydrogen atom or the like]. The method for producing the optically active compound uses the optically active substance as an asymmetric catalyst. PCOPYRIGHT: (C)2006,JPO&NCIPI
