Synthesis of the α-primeveroside of methyl salicylate
Summary1. An anomer of a natural glucoside — monotropitoside — has been synthesized for the first time.2. This method is suitable for the synthesis of anomeric oligosides of phenols.

Bei der Umsetzung von Tritylzuckern mit 2-Trichloracetyl-triacetyl-glucopyranosyl-chlorid in Gegenwart von Silberperchlorat erhalt man trennbare Gemische von α-und β-konfigurierten Disacchariden im Verhaltnis 1:1.
Preparation of Acetobrome-Sugars
THE preparation of acetobrome-sugars involves generally the use of hydrogen bromide dissolved in glacial acetic acid or acetic anhydride. These solutions are very disagreeable to handle and to prepare; we therefore tried to circumvent their use, and after some preliminary experiments found a really satisfactory way of doing so.
