    摘要： A method for producing an optically active erythro-3-amino-2-hydroxybutyric ester as an important intermediate of pharmaceutical agents, specifically HIV protease inhibitor, in high purity and in high yield. The method includes producing an optically active erythro-3-amino-2-hydroxybutyric ester by oxidizing the hydroxyl group at the 2-position of an optically active 3-amino-2-hydroxybutyric ester, optically active at the 3-position, as represented by formula (I): ##STR1## (wherein R.sup.1 represents a phenyl group or a cyclohexyl group; R.sup.2 represents a protective group and R.sup.3 represents an unsubstituted or substituted alkyl residue; the steric configuration of *1 represents S configuration or R configuration), and then reducing erythro-selectively the resulting product by using aluminum alkoxide.

    摘要： A new process step for purifying water from a small amount, particularly a last trace amount, of organic impurities included in total organic carbon (TOC) content is incorporated into known processes for the preparation of ultra pure water comprising one or more previous filtration steps and a series of purification steps known per se. The new step comprises irradiating the water to be treated with a light in the presence of a photocatalyst comprising an inorganic semiconductor selected from TiO.sub.2, SrTiO.sub.3 and CdS in fine particulate form and a noble metal and/or an oxide thereof selected from Pt, Pd, Ru, RuO.sub.2 and Rh deposited on said semiconductor particles for a period of time sufficient to oxidatively decompose the organic impurities, resulting in a decrease in TOC content of the water to a level lower than the minimum detection level of TOC detectors, typically
