FIELD: organic chemistry. SUBSTANCE: saccharose is used as reagent 1, oxide of tin dibutyl being used as reagent 2. Said reagents interacts at 75-125 C, simultaneously water being removed. The process is carried out in mixture of polar aprotic solvent and organic liquid, 1,3-di-(6-o-saccharose)-1,1,3,3-tetra(hydrocarbyl)di-stanoxane being obtained. Anhydride of carboxylic acid is used as reagent 3. During acylation desired product is isolated. EFFECT: improves efficiency of method. 3 cl, 2 tbl
