Cu(II)-catalyzed [4+2]-cycloadditions occur between Cu-benzopyryliums and substituted isoxazoles with the regioselectivity on the C(3,4)-carbons of isoxazoles. We postulate that a prior coordination of isoxazoles with Cu(OAc)2 increases the I-bond character of the C(3,4) carbons to become an effective 2I-donor. In this reaction sequence, 3,5-disubstituted isoxazoles yield alpha,I-dicarbonylnaphthalenes whereas, 5-substituted isoxazoles deliver alpha,I-dicarbonyl-beta-aminonaphthalenes. For unsubstituted isoxazole, its cycloaddition chemoselectivity is switched to the C(4,5)-addition regioselectivity to yield alpha-carbonyl-I-cyanonaphthalene derivatives.
