FIELD: chemistry.
SUBSTANCE: invention concerns organic chemistry, particularly method of obtaining spiro[3,4]oct-6-ylformiate. Method 
(1) involves interaction of methylenecyclobutane with triethylaluminium (AlEt3) in the presence of zirconocene dichloride catalyst (Cp2ZrCl2) at molar ratio of methylenecyclobutane: AlEt3:Cp2ZrCl2=10:(11-15):(0.5-0.7) in argon atmosphere at room temperature and atmospheric pressure in hexane for 7 hours, with further addition of copper chloride catalyst (CuCl) in amount equimolar to Cp2ZrCl2, and alkylformiate of the general formula HCO2R (where R=Et, n-Pr, n-Bu) thrice exceeding amount of AlEt3, to reaction mass at -15°C, further stirring at room temperature for 8-10 hours, and acid hydrolysis of reaction mass. Total output of end product after acid hydrolysis of reaction mass reaches 73-89%.
EFFECT: possible application in fine organic synthesis and production of paint coating materials and bioactive substances.
