Niharika, Pedireddi,Satyanarayana, Gedu
supporting information, p. 971 - 979 (2018/02/22)
An efficient one-pot synthesis of indenes from simple starting materials is presented. This process involves a dual C–C bond formation through an intermolecular Heck coupling reaction followed by acid-mediated intramolecular cyclodehydration. The strategy
Rhodium(II)- or Copper(I)-Catalyzed Formal Intramolecular Carbene Insertion into Vinylic C(sp2)?H Bonds: Access to Substituted 1H-Indenes
Zhou, Qi,Li, Shichao,Zhang, Yan,Wang, Jianbo
supporting information, p. 16013 - 16017 (2017/11/27)
A rhodium(II)- or copper(I)-catalyzed formal intramolecular carbene insertion into vinylic C(sp2)?H bonds is reported herein. This method provides straightforward access to 1H-indenes with high efficiency and excellent functional-group compatibility. Mechanistically, the reaction is proposed to involve the following sequence: metal carbene formation, intramolecular nucleophilic addition of the double bond to the electron-deficient carbene carbon atom, dearomatization, and finally a 1,5-H shift.
Synthesis of indenes via aluminum chloride-promoted tandem Friedel-Crafts alkylation of arenes and cinnamaldehydes
Kheira, Haiouani,Li, Pingfan,Xu, Jiaxi
, p. 168 - 174 (2014/06/09)
A series of substituted indenes were synthesized from arenes and cinnamaldehydes via aluminum chloride-promoted tandem Friedel-Crafts alkylation. The scope and limitation of the tandem reaction were explored. A plausible reaction mechanism is also discuss
