Novel 5H-indolo[2,3-b]quinoline O-aminoglycosides were synthesized in order to check the hypothesis that the construction of hybrids composed of the active 5H-indolo[2,3-b]quinoline chromophore and daunosaminyl or acosaminyl moiety may result in the cytot

Seven daunorubicin analogs containing α-L-, α-D-, and β-D-glicosidic linkages, in which the natural occuring sugar (L-daunosamine) was replaced by diastereomeric 3-amino-2,3,6-trideoxyhexoses (3-epi-L-daunosamine, D-acosamine, D-daunosamine, D-ristosamine, and 3-epi-D-daunosamine), were prepared.In all cases, glycosidation with daunomycinone was performed in the presence of p-toluenesulfonic acid starting from 1-O-acetyl-2,3,6-trideoxy-4-O-p-nitrobenzoyl-3-trifluoro-acetamidohexopyranoses (prepared from the corresponding methyl 3-amino-2,3,6-trideoxyhexopyranosides) or from 1,5-anhydro-2,3,6-trideoxy-4-O-p-nitrobenzoyl-3-trifluoroacetamidohex-1-enitols (prepared from glycosals or pseudoglycals, the 3-amino group being introduced by substitution with sodium azide and subsequent reduction).Glycosidation was followed by removal of the protecting groups.
