    Description / Table of Contents: Zusammenfassung Es wurde die Zersetzung von Diacetylmorphin unter verschiedenen Bedingungen (pH-Wert, Temperatur) untersucht. Die Quantifizierung der Zersetzungsprodukte erfolgte mit HPLC und Capillar-GC. Bei allen Zersetzungsversuchen konnte die Bildung von 3-O-Acetylmorphin neben 6-O-Acetylmorphin und Morphin nachgewiesen werden. Für illegale Heroinproben wurden Verhältniszahlen aus den Konzentrationen der beiden Isomere bestimmt. Ihre Verwendung zur Charakterisierung von Heroinproben wird diskutiert.
    Notes: Summary The decomposition of diacetylmorphine under various conditions (pH-value, temperature) was studied. The decomposition products were quantified by means of HPLC and capillary GC. 3-O-Acetylmorphine was identified in all decomposition tests besides 6-O-acetylmorphine and morphine. Ratios of the concentrations of the two acetylmorphine isomers were determined for illicit heroin samples. The application of the ratios for characterizing heroin samples is discussed.

    Description / Table of Contents: Polysaccharide Analogues, I. Synthese of 7-Amino-2,6-anhydro-7-desoxy-D-glycero-L-glycero-D-gulo-heptonic AcidSyntheses of 7-amino-2,6-anhydro-7-deoxy-D- glycero-L-manno-heptonic acid (12a) and 7-Amino-2,6-anhydro-7-deoxy-D- glycero-D-gulo-heptonic acid (12b) are described. The amino acids 12a and b may be used as monomers in the synthesis of polysaccharide analogues linked together by amide groups. Starting materials are the nitriles 1a und b which are transformed into the esters 3a and b. Selective tosylation of the primary hydroxyl groups via the trimethylsilyl ethers 4a and b followed by azide exchange yields the 7-azido derivatives 11a and b. The amino acids 12a and b are obtained by catalytic hydrogenation of 11a and b.
    Notes: Die Synthese von 7-Amino-2,6-anhydro-7-desoxy-D-glycero-L-manno-heptonsäure (12a) und 7-Amino-2,6-anhydro-7-desoxy-D-glycero-D-gulo-heptonsäure (12b) wird beschrieben. Die Aminosäuren 12a und b sind potentielle Monomereinheiten für die Darstellung von Polysaccharid-analoga mit Amidstruktur. Ausgangsprodukte sind die Nitrile 1a und b, die in die Ester 3a und b übergeführt werden. In den pertrimethylsilylierten Derivaten 4a und b können die primären Hydroxylgruppen spezifisch freigesetzt werden. Die Umsetzung von 5a und b mit p-Toluolsulfochlorid und Austausch der p-Toluolsulfonylgruppe gegen Azid liefert die Derivate 11a und b. Die Aminosäuren 12a und b werden durch katalytische Hydrierung von 11a und b dargestellt.

    Notes: A New Synthesis of 4-Deoxy-D-glucoseA modified and improved method for the synthesis of 4-deoxy-D-glucose (4) is described. The key product is methyl 2,3,6-tri-O-acetyl-4-benzoylthio-4-deoxy-α-D-galactopyranoside (3) which readily undergoes reductive desulfurization with Raney nickel. Subsequent deacetylation and hydrolysis yield 4-deoxy-D-glucose (4).
