Abstract

1,2-Dihydronaphthalin-Derivate 3 mit einem Oxosubstituenten in 1-Position können durch Cu(OTf)2-katalysierte [4+2]-Cycloadditionen von o-Alkinyl(oxo)arenen 1 an Olefine 2 synthetisiert werden (siehe Schema). Vermutlich verlaufen diese Reaktionen über ein Benzo[c]pyrylium-Kupfer(I)-Intermediat.
