2-Azido-3-arylacrylates react with α-diazocarbonyl compounds and triphenylphosphine to furnish isoquinolines in 60−92% yields. The tandem process involves a Wolff rearrangement, an aza-Wittig reaction, and an electrocyclic ringclosure. The procedure is efficient, rapid, and general, and the substrates are readily available.

Thermal decomposition of vinylazides (1a–c) gives isoquinolines (3), benzazepines (4), or aziridines (5) and (6) by preferential reaction at the unsaturated substituent; removal of this unsaturation as in the epoxides (1d,1e) leads exclusively to 4-substituted indoles.
