The PMR spectroscopic properties (250 MHz) for cycloadducts of diphenylnitrilimine towards 1,2-dihydronaphtalenes substituted at the C¹-carbon atom have been studied.The data allow us to determine the stereochemistry of the cycloaddition reaction: the approach of the dipole occurs from the less hindered diastereotopic side of the dipolarophile.The conformation of cyclohexenic moiety of the cycloadducts is an half-boat conformation.
