Synthesis of phenethylenamides and their radical cyclization to 3- benzazepines
Cid, Maria Magdalena,Dominguez, Domingo,Castedo, Luis,Vazquez-Lopez, Ezequiel M.
, p. 5599 - 5610 (1999)
Synthetic approaches to enamides, intermediates of use in the synthesis of natural products, were studied as well as their 7-endo-trig radical cyclization to 3-benzazepines.
Formation of indoles, dihydroisoquinolines, and dihydroquinolines by ruthenium-catalyzed heterocyclizations
Varela-Fernández, Alejandro,Varela, Jesús A.,Saá, Carlos
, p. 3285 - 3295 (2013/01/15)
Indoles, dihydroisoquinolines, and dihydroquinolines were efficiently prepared by ruthenium-catalyzed heterocyclizations of aromatic homo- and bis-homopropargyl amines/amides in the presence of an amine/ammonium base-acid pair. These regioselective 5-endo and 6-endo cyclizations most probably occur by nucleophilic trapping of key ruthenium-vinylidene intermediates. Georg Thieme Verlag Stuttgart · New York.
Intramolecular cyclization of ortho-alkynylanilines by Rh(I)-catalyzed hydroamination to yield benzo(dipyrroles)

The methylene-bridged Rh(I) dicarbonyl complex, [Rh(bim) (CO)2+ BPh4-] (1) (bim = bis(N-methylimidazol-2-yl)methane), is an effective catalyst for the intramolecular hydroamination of selected ortho-alkynylanilines to give a range of benzo(dipyrroles).
