Secondary products from intramolecular cycloadditions of azidoalkyl enol ethers and azidoalkyl vinyl bromides. 1-Azadienes, their reactions with diphenylketene, and radical cyclizations to form bi- and tricyclic lactams
Azidoalkyl enol ethers undergo intramolecular 1,3-dipolar cycloaddition to generate stable triazolines; in contrast, the cycloadducts formed by heating analogous azidoalkyl vinyl bromides are unstable with respect to elimination of N2 and HBr, affording 1-azadienes (2-alkenyl cyclic imines). These p...
