Facile assembly of 11 H -indolo[3,2-c]quinoline by a two-step protocol involving a regioselective 6- endo -cyclization promoted by the hendrickson reagent

Xu, Min,Hou, Qiwen,Wang, Shaozhong,Wang, Huaqin,Yao, Zhu-Jun

, p. 626 - 634 (2011/04/15)

An expedient approach was developed to construct the 11H-indolo[3,2-c] quinoline scaffold starting from acyclic alkyne substrates. The five- and six-membered nitrogen-containing rings in the tetracyclic skeleton were elaborated efficiently by gold(III)-ca
