Monosaccharides Containing Nitrogen in the Ring, XXXVII. Synthesis of 1,5-Dideoxy-1,5-imino-D-galactitolThe oxime mixture 3 + 5 of the 1,6-anhydro-furanose-5-ulose 2 can be preferably hydrogenated to the 5-amino sugar 9a with galacto-configuration. Hydrolysis of the benzyloxycarbonyl compound 9b gives the sugar 7 containing nitrogen in the pyranose ring, which yields by hydrogenation 1,5-dideoxy-1,5-imino-D-galactitol (13).
Notes:
Das Oximgemisch 3 + 5 der 1,6-Anhydro-furanos-5-ulose 2 läßt sich bevorzugt zum 5-Amino-Zucker 9a der galacto-Konfiguration hydrieren. Hydrolyse der Benzyloxycarbonyl-Verbindung 9b liefert den Zucker 7 mit Stickstoff im Ring, aus dem 1,5-Didesoxy-1,5-imino-D-galactit (13) erhältlich ist.
