Just add light and air: Structurally diverse N-arylindoles can be prepared from readily prepared o-styryl anilines through visible-light photocatalysis. The reaction, which is conducted open to air, is mediated by [Ru(bpz) 3](PF6)2 (bpz=2,2'-bipyrazine) and involves both C-N bond formation and aromatization (see scheme). Using suitably substituted substrates, a 1,2-carbon shift can be also incorporated into this cascade reaction. Copyright

We report a new metal-catalyzed 6-endo-dig cyclization of cis-4,6-dien-1-yn-3-ols, which produces substituted benzene and naphthalene derivatives with structural reorganization. In this process, we observe a 1,3-alkylidene migration via cleavage of the olefin double bond of the starting substrates. The ease and reliability of this cyclization are manifested by its compatibility with a wide array of diverse substrates and several π-alkyne activators, including PtCl2, Zn(OTf)2, AuCl, and AuCl3.
