Abstract
The structures of two [2π + 2π] cycloaddition adducts, [endo-3-exo-cyano-7-methoxytricyclo[4.2.1.0 2,5 ]-non-7-ene and dimethyl exo, endo-5-aza-tetracyclo-[7.2.1.0 2,8 .0 3,7 ]dodec-10-ene-4,6-dione-10,11-dicarboxylate, were determined and the stereo- and regiochemistry of each molecule was established. One adduct possesses an endo ring fusion while the other was found to be exo. In both structures molecules form centrosymmetric dimers as a result of weak intermolecular, non-bonded interactions of the type C=O... H-C.
