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 H-1 NMR spectra.
