NEW MATERIAL:An optically active lactic acid derivative shown by formula I or formula II (R is 1W18C straight-chain, branched or cyclic saturated or unsaturated hydrocarbon group; water is asymmetic carbon atom; A is chemically active substituent group; R' is 4W18C alkyl or alkoxy; B is group shown by formula IIIWIV). n EXAMPLE: p-Hydroquinonemono(butoxypropyl) ether. n USE: An optically active intermediate changing a molecular structure readily, which is used for synthesizing a functional material necessary for an optical element having optical activity characteristically. n PREPARATION: A compound shown by formula V is reacted with hydroquinone to give a compound shown by formula I (A is OH). n COPYRIGHT: (C)1987,JPO&Japio |
