Abstract

1,3-Dipolar cycloaddition of 6,7-dialkoxy-3,4-dihydroisoquinolinium salts to dipolarophiles of azomethin- and alkene type have been investigated. The regioselectivity of the reactions rationalized on the basis of the perturbation theory, using CNDO/2 and CNDO/S approximations. Good agreement between the calculated and experimental results was achieved only when a distance of 3 Å in the transition state between the molecules was chosen. The exo/endo ratio of the cycloadducts has also been rationalized.
