<p>Method of Producing (S)-Glyceraldehyde Acetonide A method of producing (S)-glyceraldehyde acetonide, which comprises reacting 3,4-O-isopropylidene-L-threonic acid or a salt thereof with hypochlorite ion or hypochlorous acid under an acid condition, a method of producing (S)-glyceraldehyde acetonide, which comprises reacting 5,6-O-isopropylidene-L-ascorbic acid or a salt thereof with an oxidizing agent to produce 3,4-O-isopropyli-dene-L-threonic acid or a salt thereof and then reacting 3,4-O-isopropylidene-L-threonic acid or a salt thereof with hypochlorite ion or hypochlorous acid under an acid condition, and a method of producing (S)-glyceraldehyde acetonide, which comprises (1) reacting L-ascorbic acid or a salt thereof with acetone or a conventional equivalent thereof to produce 5,6-O-isopropylidene-L-ascorbic acid or a salt thereof; (2) reacting 5,6-O-isopropylidene-L-ascorbic acid or a salt thereof with an oxidizing agent to produce 3,4-O-isopropylidene-L-threonic acid or a salt thereof; and (3) reacting 3,4-O-isopropylidene-L-threonic acid or a salt thereof with hypochlorite ion or hypochlorous acid under an acid condition.</p> |
