Abstract

Abstract : A metal-free cascade reaction was developed for the synthesis of indolo[1, 2- a ]quinoline derivatives from arylsulfonyl hydrazides and 1-(2-(arylethynyl)phenyl)indoles in the presence of TBAI/TBHP. Abstract : A metal-free cascade reaction was developed for the synthesis of indolo[1, 2- a ]quinoline derivatives from arylsulfonyl hydrazides and 1-(2-(arylethynyl)phenyl)indoles in the presence of TBAI/TBHP. Impressively, these products exhibit excellent fluorescence properties, which is promising for cell imaging.
