The stereospecific gold(I)-catalyzed nucleophilic cyclization of β-monosubstituted o-(alkynyl)styrenes to produce C-1 functionalized 1H-indenes including challenging substrates and nucleophiles, such as β-(cyclo)alkyl-substituted o-(alkynyl)styrenes and a variety of alcohols as well as selected electron-rich aromatics, is reported. DFT calculations support the stereochemical outcome of the process

The gold(I)-catalyzed oxycyclization of β-aryl monosubstituted o-(alkynyl)styrenes gives rise to 1-α-methoxy or 1-α-hydroxybenzyl-1H-indenes in a diastereospecific way. In contrast to β,β-disubstituted o-(alkynyl)styrenes, the stereochemical outcome of this process, diastereospecific reaction supports the higher contribution of a gold intermediate with a cyclopropylcarbene-like character.
