Abstract
The present invention relates to a method for synthesizing a 3-phenyl-2,3,4,8,9,10-hexahydropyrano[2,3-f]chromene derivative and an optical isomer thereof, and an intermediate Compound which may be used for the synthesis method, and when the method and the intermediate Compound are used, the 3-phenyl-2,3,4,8,9,10-hexahydropyrano[2,3-f]chromene derivative and the optical isomer thereof may be effectively synthesized.
