    摘要: The objective of the present invention is to provide an optically active imidazolidinone derivative widely usable for synthesizing an optically active amino acid, a method of easily producing the derivative, and a method of easily producing an optically active amino acid by using the derivative. The objective can be achieved by producing an optically active amino acid using a novel optically active imidazolidinone derivative represented by a general formula (3) and the like. According to the method of the present invention, an optically active imidazolidinone derivative can be obtained by preferential crystallization from a mixture of isomers of the imidazolidinone derivative. Therefore, an optically active amino acid can be easily and stereoselectively produced without cumbersome procedures required for the conventional methods, such as resolution of diastereomers, synthesis from an optically active amino acid and resolution of isomers by silica gel column chromatography.

    摘要: An information recording/reproducing apparatus for reproducing picture and audio signals in synchronization reproduces audio/still-picture information which has been recorded onto a recording medium in a receiving order and in a time-sharing manner. Still-picture reproduction circuitry is provided for reproducing the still-picture from a designated reproduction starting position on the recording medium in accordance with a designated still-picture reproduction starting position. Detection circuitry is provided for detecting an audio synchronization signal from audio packets positioned on the recording medium after the still-picture packet to be reproduced. Sound reproduction circuitry is provided for reproducing audio data from an audio packet positioned on the recording medium after the audio packet which contains the detected audio synchronizing signal.
