Carbolithiation of N-alkenyl ureas and N-alkenyl carbamates
Lefranc, Julien,Minassi, Alberto,Clayden, Jonathan
, p. 628 - 632 (2013/05/21)
N-Alkenyl ureas and N-alkenyl carbamates, like other N-acyl enamines, are typically nucleophilic at their β-carbon. However, by incorporating an α-aryl substituent, we show that they will also undergo attack at the β-carbon by organolithium nucleophiles,
