  • Title: Decarboxylative aldol reactions of allyl beta-keto esters via heterobimetallic catalysis.
    Author: Lou S, Westbrook JA, Schaus SE.
    Journal: J Am Chem Soc; 2004 Sep 22; 126(37):11440-1. PubMed ID: 15366881.
    Abstract:
    Mild and selective heterobimetallic-catalyzed decarboxylative aldol reactions involving allyl beta-keto esters have been developed. The reaction is promoted by Pd(0)- and Yb(III)-DIOP complexes at room temperature and involves the in situ formation of a ketone enolate from allyl beta-keto esters followed by addition of the enolate to aldehydes. The reaction is a new example of heterobimetallic catalysis in which the optimized reaction conditions require the addition of both metals.
