Ts. Kuznetsova et al., SYNTHESIS OF ALICYCLIC DERIVATIVES OF SPIROPENTANE BASED ON 1,5-CYCLOOCTADIENE, Russian chemical bulletin, 45(7), 1996, pp. 1662-1666
Methods for the synthesis of alicyclic derivatives of spiropentane by
[1+2] cycloaddition of halo- and dihalocarbenes to 1,5-cyclooctadiene
followed by dehydrohalogenation and cyclopropanation of the olefins fo
rmed are described.
