Abstract: Enamides equipped with N-acyliminium ion precursors were obtained through reduction of ynamides tethered to N-imides. Intramolecular TMSOTf-mediated trapping of N-acyliminium ions provided a variety of polyfunctionalized medium-sized diaza-heterocycles of putative pharmacological interest. read more here.
