Significance

This is a nice report for the indirect allylation of ketones. The authors expertly use enamine chemistry to access high regio- and enantioselectivity. Use of a iridium(cod)-phosphoramidite complex gave the branched product with high selectivity. Interestingly, ZnCl2 was added to trap the liberated isopropanol.
