Diels-Alder reactions of R-(-)-carvone with isoprene using different Lewis acids as catalysts have been studied. The best results were obtained with EtAICI2 at 25 Β°C for 48 hours. The yields are quantitative and the d.e. is 86.8%. Regioselective dihydroxylation at the endocyclic double bond of the c
