Nickel-catalyzed cocyclotrimerization of oxa- and azabenzonorbornadienes with alkynes: reaction with multiple synthetic applications

[[abstract]]Oxa- and azabenzonorbornadienes react with alkynes in the presence of nickel complexes to give the corresponding [2 + 2 + 2] cycloadducts; these reactions can be applied to the construction of multiple fused rings, the preparation of precursors of isobenzofurans and isoindoles and aromatic compounds.[[fileno]]2010326010022[[department]]化學
