A moderate asymmetric induction is observed when chiral diphosphine ligands are used for rhodium. Indene/indole-fused compounds are synthesized by a similar reaction of [(2-acetylphenyl)ethynyl]anilines. The domino-type 5-endo/5-exo cyclization reaction is extended to substrates having two phenolic hydroxy groups. A linearly-fused array of five- and six-membered rings is constructed. Fused and linked benzofurans possessing 2-cyanoethyl side chains are also synthesized through sequential formation of C–O and C–C bonds. }, number={12}, journal={CHIMIA}, author={Matsuda, Takanori and Abe, Shinya and Ito, Hirotaka and Tsuboi, Tomoya and Kirikae, Haruki and Murakami, Masahiro}, year={2018}, month={Dec.}, pages={888} }
