Nitro-facilitated '5-exo-dig' intramolecular cyclisation of 2-(2-nitrophenylethynyl)benzoic acids: A new total synthesis of indeno[1,2-b]indoles

2-(2′-Nitrophenylethynyl)benzoic acid esters, obtained by Sonagashira coupling of o-bromobenzoates to 2-(2′-nitrophenyl)acetylenes, were converted into indeno[1,2-b]indoles by a two-step sequence, through the corresponding 2-nitrophenyl-1,3-indandiones.
