the generality of gold versus silver catalyzed intramolecular hydroarylation reactions of 3-[(3-arylprop-2-ynyl)oxy]benzenederivatives in terms of rings substitution were investigated. Only products deriving from 6-endo cyclization were exclusively formed. The features of substituents had a considerable effect on the reaction outcome in the presence of silver catalysis, whereas gold catalysis revealed
A gold (I)‐catalyzed approach for the construction of polycyclic chromene cores was developed. The reaction proceeds in good to excellent yields under mild condition. In the presence of unsymmetrically substituted propargylic ethers a good selectivity has been achieved.
