FIELD: organic chemistry. SUBSTANCE: product: anthracycline glycosides of the general formula (A): $$$ where X - direct or branched $$$-alkyl or benzyl group having (S)- or (R)-configuration at $$$-carbon atom, and diiodocompound of the general formula (C): $$$ where X - as indicated above. Compound (A) is synthesized by interaction of doxorubicin with diiodocompound (C) which is synthesized by interaction of arabinose with an alcohol X-OH followed by periodate oxidation of the obtained product. The obtained dialdehyde derivative of the formula: $$$ is reduced to the corresponding dihydroxy-derivative followed by sulfonation and iodination of the obtained sulfonated derivative. EFFECT: improved method of synthesis. 7 cl, 6 tbl
