13C NMR spectra of exo,exo- and exo,endo-stereoisomers of tetracyclo[6.2.1.02,7.13,6]dodecane

Conclusions The¹³C NMR spectra of the exo, exo- and exo, endo-isomers of tetracyclo[6.2.1.0^2,7.1^3,6]dodecane were studied. The chemical shift of the bridge carbon depends on the configuration of the geometric isomer and can be used as a criterion to identify the stereoisomers in polycyclic systems with a norbornane fragment.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 924–926, April, 1977.The authors express their gratitude to S. S. Berman and A. A. Petrov for supplying the compounds.
