FIELD: chemistry.
SUBSTANCE: reaction is carried out in a two-phase system: aqueous potassium hydroxide solution - toluene at room temperature for 3-11 hours with further extraction of the product with acetone and extraction of the product from the organic layer. Extraction of the products from the organic layer and purification is carried out by deposition into ethyl alcohol.
EFFECT: invention enables to obtain novel propargyl esters of arabinogalactan by realising the method under mild conditions.
