An unusual domino reaction of 2-isocyanophenyloxyacrylate and aryne has been disclosed. The present strategy experiences nucleophilic addition, Michael addition, carbon-oxygen cleavage, and cyclization, thus enabling the quick aryne vicinal difunctionalization by the installation of a benzoxazole and an olefin.

The dimethyltitanocene methylenation of N-acylamides derived from ortho-vinylanilines, ortho-allylaniline, and ortho-vinylbenzylamine provides the corresponding enamides, which upon exposure to the second generation Grubbs ruthenium catalyst give access to indoles, 1,4-dihydroquinolines, and 1,2-dihydroisoquinolines, respectively. This sequential protocol also allows the synthesis of dihydrobenzoazepines, although the ring-closing metathesis (RCM) step is complicated by the alkene isomerization processes. From certain substrates, the direct annulation is observed in the titanium-mediated step, which is likely to occur through an olefin metathesis-intramolecular olefination sequence.

Generation of the title radicals was effected by flash vacuum pyrolysis of benzyl phenyl ethers, and O-allyl ethers, respectively.The major products are formed by a multi-step sequence involving (i) intramolecular hydrogen transfer from the alkylamino group to the initial radical cemtre, (ii) rearrangement of the resulting aminoalkyl radical, (iii) expulsion of the nitrogen residue to give a bezyl radical which leads to products.
