The direct catalytic asymmetric aldol reaction using aldehydes and unmodified ketones is described for the first time herein. This reaction was first found to be promoted by 20 mol % of anhydrous (R)-LLB (L ) lanthanum, L ) lithium, B ) (R)-binaphthol moiety) at -20 ยฐC, giving a variety of aldol pro

In the synthesis of complex molecular targets, the ability to control the stereoselectivity of the aldol reaction has raised this process to a level of prominence shared by few reactions. In most cases, however, the stoichiometric transformation of the active methylene partner into its enolate or an
