ABSTRACT OF THE DISCLOSURE The present invention relates to a process for producing cyclobutane derivatives represented by general formula (28): Image (28) (wherein R represents a substituent; R2 represents an electron attracting group and Nu represents a substituent corresponding to nucleophilic reagent), by reacting a compound represented by general formula (27): Image (27) (wherein R has the same significance as defined above and R1 represents an electron attracting group) with nucleophilic reagents Nu? in a solvent. The compounds of formula (28) are useful as intermediates for synthesis of, for example, 9-[2,3-bis(hydroxymethyl)cyclobutan-1-yl]guanine which is expected to be useful as an antiviral agent.
