Key words

α-hydroxyketones - dual metal catalysis - asymmetric allylation

Significance

A dual metal-catalyzed asymmetric allylation of α-hydroxyketones is described. Chiral iridium and zinc complexes are employed for this transformation to furnish stereodefined α-hydroxyketones.


#

Comment

Multi-metal asymmetric catalysis is a newly emerging field in catalysis. Exploitation of the preferential binding affinity of chiral ligands to specific metal centers allows chemo- and stereoselective formation of the desired products.
