A three-step sequence has been developed for converting o-nitrobenzaldehydes into 2nitroindoles. The key step involves the thermolysis of 2-(o-azidophenyl)nigoethylene (10) in xylenes which gives 2-nitroindole (4) in 54% yield, akin to the classic Sundberg indole synthesis. This p~ure has also been
