A protocol for the synthesis of α-tertiary amines was developed by iterative addition of carbon nucleophiles toN,N-dialkyl carboxamides. Nucleophilic 1,2-addition of organolithium reagents to carboxamides forms anionic tetrahedral carbinolamine (hemiaminal) intermediates, which are subsequently trea...
