    Notes: With alkylbenzylamine D-glucose undergoes AMADORI-rearrangement to 1-alkyl-benzylamino-1-deoxy-D-fructose. Catalytic hydrogenolysis of the benzyl group gives rise to 1-alkylamino-1-deoxy-D-fructose (alkyl-fructosamine). In this way, the methyl, ethyl and butyl derivatives of fructosamine have been prepared in crystalline form. With isocyanic acid and rhodanic acid the 1-alkylamino-1-deoxy-D-fructoses are converted into imidazole derivatives, as expected for substances of the α-aminoketone type.

    Notes: The reactions of isocyanic acid and of thiocyanic acid with the products of AMADORI rearrangements are described. Thiocyanic acid, especially, is well suited for the characterization of fructosamines. By etherification of the mercapto group and exposure to oxidizing agents, the 2-mercapto-imidazoles can be used for preparation of certain imidazole derivatives which are otherwise difficult to obtain, e.g. 4-formyl-imidazole.

    Zum Verständnis der Epoxydöffnung an Pyranose-Ringen (1960)

    Notes: Die Epoxydöffnungen an Pyranose-Ringen wurden konformationsanalytisch untersucht. Den Epoxyden wird Semisesselkonformation zugeschrieben. Die meisten experimentellen Ergebnisse der Literatur bestätigen die Annahme, dass der Angriff axial erfolgt und dass im Laufe der Substitutionsreaktion keine Konformations-änderung stattfindet.
