Abstract

Neat Et2Zn, Ph2Zn, and highly concentrated Me2Zn are highly reactive organozinc reagents, which are commercially available in bulk quantities. We here report a catalytic enantioselective Et2Zn, Ph2Zn, and Me2Zn addition to ketones and aldehydes under solvent free or highly concentrated conditions without Ti (Oi-Pr) 4 as a conventional activator of organozinc reagents. The desired optically active tertiary and secondary alcohols were ...
