Effect of the conditions on the enantiomeric purity, overall yield, and isomeric composition of chiral polybromonorbornene Diels-Alder adducts of polybromocyclopentadienes and (-)-menthyl acrylate was studied. Enantiomerically pure polybromonorbornenecarboxylic acids were obtained by resolution of the corresponding racemates through diastereoisomeric salts with l-ephedrine. The structure of the products was confirmed by the IR and 1H NMR spectra.

The diene synthesis reaction was realized between hexabromo-1,3-cyclopentadiene and dienophiles of the acrylic series, and it was shown that the reaction takes place strictly stereospecifically with the formation of the endo adducts.The kinetics of the reaction were studied, and the activation parameters were determined.In the investigated reaction series the hexabromo-1,3-cyclopentadiene is the diene-acceptor.
