Significance

The authors disclose an application of the rhodium diene catalyst to the addition of aryl nucleophiles to N-tosyl ketimines. These ­substrates comprise a relatively challenging class of electrophiles for asymmetric organometallic ­additions, and as a result, only a few examples of allylboronate and dialkylzinc additions are known. The resulting products are chiral amines containing a quaternary stereocenter.
