Catalytic enantioselective alkyl and aryl addition to aldehydes and ketones with organozinc reagents derived from alkyl Grignard reagents or arylboronic acids

A highly practical, catalytic enantioselective alkyl and aryl addition to aldehydes and ketones with organozinc reagents, which were prepared in situ from commercially available Grignard reagents or arylboronic acids, was developed. A chiral phosphoramide ligand was essential for promoting the addition reactions in high yields with high enantioselectivities.
