SUBSTITUTIONS D'ESTERS ALLYLIQUES: PREPARATION DE GLYCALS AMINES EN C-3 ET ETUDE DE LEUR GLYCOSIDATION ACIDO-CATALYSEE. APPLICATION A L'HEMISYNTHESE DE GLYCOSIDES DU GROUPE DES ANTHRACYCLINES

3-Amino-1,5-anhydro-2,3,6-trideoxy-L-arabino- and -L-ribo-hex-1-enitol were prepared by substitution of the allylic ester function of 1,5-anhydro-3,4-di-O-benzoyl-2,6-dideoxy-L-arabino-hex-1-enitol with sodium azide, followed by reduction with lithium aluminium hydride.Glycosidation was performed with various alcohols, in particular daunomycinone.In the latter case, the partial synthesis of 4'-epi- and 3',4'-epi-daunorubicines was accomplished in three major steps.

HEMISYNTHESE DE NOUVEAUX GLICOSIDES ANALOGUES DE LA DAUNORUBICINE

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.
