Abstract
There are described sugar derivatives of the formula I ##STR1## that have immuno-stimulating action and that contain as inventive element at least one radical A.sup.1 or A.sup.2. These radicals A.sup.1 and A.sup.2, which may be constituents of the radicals R.sup.1, R.sup.2, R.sup.4, R.sup.6, R.sup.9, R.sup.10 or R.sup.12 according to formula I, are defined as follows: PA0 A.sup.1 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 substituent, forms a five-membered ring or represents ortho- or ortho/meta-substituted aroyl. A.sup.2 represents lower alkoxy substituted by aryl, heteroaryl or heteroarylthio. Also described are processes for the manufacture of the compounds of the formula I and novel intermediates.
