REGIOSELECTIVITY AND SPECIFICITY IN CYCLOADDITION OF DIPHENYLNITRILIMINE

Kitane, Said,Kabula, Tshiamala,Vebrel, Joel,Laude, Bernard

, p. 1217 - 1218 (1981)

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