amino acids. In this article, the asymmetric aldol-reduction reaction leading to 1,3-diols (known as the aldol–Tishchenko reaction) has been performed with an elaborated family of ligands. This unique tandem reaction was catalysed by chiral Yb complexes that promote both the aldolreaction of unactivated carbonyl compounds and the Evans–Tishchenko reduction of the aldol intermediates. 1,3-anti-Diols with
