carbonyl donors, that is, ketones and aldehydes with unbiased N,O‐acetals, is described. Sn(NTf2)4 is an optimal catalyst to promote this challenging transformation at low loading and the reaction shows promising scope. A comprehensive and rational evaluation of this reaction has led to the establishment of an empirical scale of nucleophilic reactivity for a broad set of ketones that should be helpful

protocol for the direct amidoalkylation of simple enolizable ketones with use of Lewis superacid Sn(NTf2)4 as a catalyst is described. Couplings of a large set of both carbonyl and N,O-acetalic substrates (mostly the simplest OH-hemiaminals) proceed with very low catalyst loadings (≤ 1 mol-%) and provide the corresponding amidoalkylated ketones in high yields (up to 99 %).
