    Description / Table of Contents: Ketosylamine Rearrangement of D-threo-Pentulose (D-Xylulose) with α-Amino Acids1)D-threo-Pentulose (1) reacts with glycin (2a), L-α-alanine (2b) or L-valine (2c) to give mixtures of the D-xylose-and D-lycxose-amino acids, from which the D-xylose-amino acids (4a-c) can be obtained pure by chromatography. 2-L-α-alanino-2-desoxy-D-lyxose (5b) and 2-D-valino-2-deoxy-D-lyxose (5c) are obtained by crystallization. The reaction of D-xylulose and glycine is investigated quantitatively.
    Notes: D-threo-Pentulose (1) reagiert mit Glycin (2a), L-α-Alanin (2b) oder L-Valin (2c) zum Gemisch der D-Xylose-und D-Lycxose-Aminosäuren, aus dem sich durch Säulenchromatographie die D-Xylose-aminosäuren (4a-c) rein gewinnen lassen. 2-L-α-Alanino-2-desoxy-D-lyxose (5b) und 2-L-Valino-2-desoxy-D-lyxose (5c) werden durch Kristallisation erhalten. Die Reaktion der D-Xylulose (1) mit Glycin (2a) wird quantitativ verfolgt.
