摘要

The [4+2]-cycloaddition of maleic anhydride to 2-tropylcyclohexanone was studied and demonstrated to afford a mixture of endo- and exo-adducts in a 7: 1 ratio in a 90% total yield. The adducts were isolated in the individual state and their structures were established by modern 1D and 2D NMR spectroscopic methods and X-ray diffraction analysis.
