Acylated sugar derivatives, processes for their manufacture, and their use Abstract There are described sugar derivatives of the formula I Image (I) that have immuno-stimulating action and that contain as inventive element at least one radical A1 or A2. These radicals A1 and A2, which may be constituents of the di als R1, R2, R4, R6, R9, R10 or R12 according to formula I, are defined as follows: A1 represents lower alkanoyl that is substituted by aryl, heteroaryl or heteroarylthio and that may be additionally substituted by an ethylene radical which, with the above-mentioned aryl or heteroaryl substi- tuent, forms a five-membered ring or represents ortho- or ortho/meta-substituted aroyl. A2 represents lower alkoxy substituted by aryl, heteroaryl or hetero- arylthio. Also described are processes for the manufacture of the compounds of the formula I and novel inter- mediates.
