Under acidic conditions, initially formed iodocyclization products undergo in situ Friedel-Crafts cyclizations, giving access to iodo-indenopyridines. The application of the vinyl halides in cross-coupling reactions has been explored, and mechanistic aspects of the cyclization are discussed.en-USCC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/Allium catalysisDiyne cyclizationIndenopyridinePyridinoindeneArticle10.1021/acs.orglett.5b00716
