The radical cascade cyclization of various 1,6-enynes with aryl radicals by electron catalysis under metal-free reaction conditions was explored. Readily available anilines were used as radical precursors, and the reactions proceeded in the absence of any transition metal. These cascades comprise three C–C bond formations, which provide polycyclic structures with extended π-systems. The photophysical properties of some of these novel compounds were investigated, and a plausible reaction mechanism is proposed.
Synthesis of 5H-1,2,3-triazolo[4,3-a][2]benzazepines from the Baylis-Hillman adducts of 2-alkynylbenzaldehydes

The facile synthesis of 5H-1,2,3-triazolo[4,3-a][2]benzazepines 5a-d by the intramolecular 1,3-dipolar cycloaddition reaction of 2-alkynylphenylallyl azides 4a-d is described. The latter were readily obtained from 2-alkynylbenzaldehydes 1a-d through the Baylis-Hillman adducts 2a-d followed by acetylation to compounds 3a-d and nucleophilic substitution by azide to compounds 4a-d.
