Abstract

Transition-Metal-Free Tunable Chemoselective N Functionalization of Indoles with Ynamides. -Two new reaction pathways of ynamides with heterocycles containing a N-unsubstituted pyrrole unit are developed using NaOtBu as the base. Either Z-indolo-etheneamides or indolo-amidines (XI) can be selectively obtained under the same reaction conditions. -(HENTZ, A.; RETAILLEAU, P.; GANDON, V.; CARIOU, K.; DODD*, R. H.; Angew.
