In order to control the regiochemistry of the cycloaddition of diphenylnitrilimine on 1,2-dihydronaphtalene and at-1 or -2 substituted derivatives and to obtain either regioisomer, we introduce a methoxycarbonyl group at the 4- or 3- position of the dipol

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.

Diphenylnitrilimine cycloaddition reactions on 1,2-dihydronaphtalenes are only regioselective.Use of 1- or 2-tetralones enamines as dipolarophiles allows to attain regiospecificity.
