ALPHA -D-PENTOFURANOSIDE DERIVATIVES, PROCESS FOR PREPARING THE SAME AND THEIR USE

摘要

alpha-D-pentofuranoside derivatives have the general formula (D), in which R stands for (C1-C4)alkyl that is non-substituted or substituted one or several times by halogen, (C1-C4)alkyl, (C1-C4)alkoxy and/or phenyl, and R1 stands for [(C6-C20)aryl]k-[(C1-C4)alkyl or [(C6-C20)]aryl]k-[(C1-C12)alkyl)(3-k)Si in which k=0 to 3, that are non-substituted or substituted one or several times by halogen, (C1-C4)alkyl, (C1-C4)alkoxy and/or (C6-C20) aryl, or preferably a benzyl that is non-substituted or substituted one or several times by the above substituents. Also disclosed are starting and intermediary compounds, up to furanosides (D) having an analogous structure, processes for preparing said furanosides and their precursors, and their use.
