| titleOfInvention | Process for producing optically active compounds that efficiently removes chiral auxiliary groups |
| abstract | (57) [Problem] To improve the usefulness or adaptability of an optically active compound by efficiently removing a chiral auxiliary group used in asymmetric synthesis from an asymmetric synthesis product. SOLUTION: An asymmetric ester (A 1 ) having two asymmetric sources is reacted with sodium methoxide in the presence of dimethyl carbonate according to the following reaction formula (1) to give an asymmetric ester ( A method for producing an optically active compound by removing a chiral auxiliary group from an asymmetric synthesis product comprising producing B 1 ) and oxazolidinone or an analog thereof (C 1 ). In the formula (1), R represents a functional group or an atomic group containing an asymmetric source constituting the desired optically active compound; Represents a hydroxyalkylamide or an oxazolidinone type chiral auxiliary, and n is an integer of 2 to 4.
