Cationic gold-catalyzed cyclizations for the preparation of complex azaheterocycles

Cationic homogeneous Au(I)-catalysts will be evaluated for the synthesis of complex N-containing cyclic compounds. Firstly, both intra- and intermolecular 1,n-enyne cyclizations will be studied, where the attack of a N-nucleophile is crucial. Secondly, the reaction between in situ formed Au-vinylidenes and N-nucleophiles will be investigated.
