Danneman, Michael W. published the artcileA Unified Approach to the Four Azaindoline Families by Inter-/Intramolecular Annulative Diamination of Vinylpyridines, Related Products of piperazines, the publication is Organic Letters (2015), 17(15), 3806-3809, database is CAplus and MEDLINE.
An operationally straightforward and metal-free inter-/intramol. oxidative diamination of vinyl aminopyridines is a common gateway to access all four azaindoline heterocycle families. 3-Amino azaindolines are formed by the reaction of ortho-vinyl N-tosyl anilines with electron-rich amines using phenyliododiacetate (PIDA) and an iodide additive.
