The project detailed in this proposal deals with asymmetric organic transformations using chiral d transition metal- and lanthanide-based catalysts. We hypothesize that enolates can add to unactivated olefins in an enantioselective fashion, using bimetallic activation. To achieve this goal, we reason that a lanthanide complex can be used as strong sigma-Lewis acid to activate the carbonyl functionality of a pronucleophile and generate an enolate (or a complexed enol), while a soft pi-Lewis acid, incorporating for instance gold or platinum, activates the olefin toward nucleophilic attack. The chirality could be borne by either complex. The result of such a reaction would be comparable to an asymmetric Michael addition, yet applied to simple alkenes. The development of this reaction would pave the way for total syntheses of natural products.
