ABSTRACT:
Compounds containing a substituted or unsubstituted allyl group directly bound to a chiral carbon atom are prepared enantioselectively. Starting reactants are either chiral or achiral, and may or may not contain an attached allyloxycarbonyl group as a substituent. Chiral ligands are employed, along with transition metal catalysts. The methods of the invention are effective in providing enantioconvergent allylation of chiral molecules.
