FIELD: organic chemistry, chemical technology. SUBSTANCE: invention describes method of combined synthesis of 1-ethyl-3,6-dialkylcycloheptaoxalanes of the formula (1) and 1-ethyl-3,5- dialkylcycloheptaoxalanes of the formula (2) where R means n-C4H9, n-C6H13; R' means n-C3H7, i-C3H7, n-C5H11, characterized by that alpha-olefins of the formula where R is given above are subjected for interaction with triethylaluminium (AlEti) in the presence of zirconacene dichloride (Cp2ZrCl2) as catalyst taken in the mole ratio : AlEt3 : Cp2ZrCl2 = 10 : (10-14) : (0.3-0.7), respectively, in argon atmosphere for 8 h followed by hexane addition, cooling reaction mass to 10 C and addition of copper monochloride (CuCl) as catalyst and aldehyde of the formula R'-CHO where R' is given above taken in the mole ratio CuCl : R'-CHO = (0.8-1.2) : (10-14), respectively, and reaction mass is stirred for 6-10 h at the room temperature under normal pressure. Synthesized compounds can be used in fine organic and metalloorganic synthesis and as co-catalysts in processes of oligomerization and polymerization of olefins and dienes. EFFECT: improved method of synthesis, valuable properties. 1 tbl
