title: CuI-catalyzed photochemical or thermal reactions of 3-(2-azidobenzylidene)lactams. Application to the synthesis of fused indoles.
abstract: Photochemical or thermal reactions of 3-(2-azidobenzylidene)-lactams afforded fused indoles such as indolo[3,2-c]quinolin-6-ones, pyrido[4,3-b]indol-1-ones and other similar compounds in moderate to high yields via cyclization-ring expansion reactions. The photolytic process was much more facile than the thermal process and could be further improved by addition of CuI.
