Alkynoic acids, in particular, 4-pentynoic acid derivatives, undergo intramolecular cyclizations to enol lactones under reaction conditions typically applied for the Cu(I)-catalyzed cycloaddition of terminal alkynes and azides (click chemistry). Starting from appropriate alkynoic acid derivatives, either enol lactones or 1,2,3-triazole

An efficient and facile Au(I)/Ag(I)-catalyzed cascade method has been developed for one-pot synthesis of the complex polycyclic heterocycles benzo[4,5]imidazo[1,2-c]pyrrolo[1,2-a]quinazolinone derivatives through treatment of the substituted 2-(1H-benzo[d]imidazol-2-yl)anilines with 4-pentynoic acid or 5-hexynoic acid. The strategy features a Au(I)/Ag(I)-catalyzed one-pot cascade process
A library of eight sequence-defined model oligomers, whose sequence is based on a (0,1) binary code, is prepared through chemoselective repeating cycles of amidification and copper-assisted alkyne-azide cycloaddition reactions from a non-modified Wang resin. This library is constructed from two
Click chemistry, and the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) in particular, is a powerful new synthetic tool in polymer chemistry and material science.
