Eine neue Methode zur Maskierung der Oxygruppen an C1 und C2 in Aldo‐pyranosen

Abstract: An Triacetyl-d-glucal kann Phenanthrenchinon addiert werdcn zu einem Phenanthrenhydrochinon-d-glucosid-anhydrid. Durch Behandlung mit Ozon laBt sich aus diesem Diphensiiure abbspalten und die Glucose in guter Ausbsute zuriickgewinnen.Vor einigen Jehren wurden innere Anhydride von Glykosiden des Glykols beschrieben'), denen man uuf Grund ihrer Entstehung und ihres Verhaltens die Formel 1 zuerteilen Ironnte.Der Diosanring ist in dieseu Subshnzen so stabil, daB eine Abspaltung deS Glyknls von der Oxygruppe a n C … Show more

“…Photochemical reactions between 1,2‐diketones and unsaturated compounds or aldehydes were reported as early as in the 1950’s [43] . In those years, 9,10‐phenanthraquinone was reacted with glucal to obtain a protected glucoside [44,45] . Later, the photocycloaddition with 1,2‐diketones was used for the synthesis of β‐hydroxy‐γ‐ketoesters [46] .…”
