  • Title: Organocatalytic Michael addition of aldehydes to gamma-keto-alpha,beta-unsaturated esters. an efficient entry to versatile chiral building blocks.
    Author: Wang J, Ma A, Ma D.
    Journal: Org Lett; 2008 Dec 04; 10(23):5425-8. PubMed ID: 19006393.
    Abstract:
    The diarylprolinol ether/HOAc-catalyzed Michael addition of aldehydes to gamma-keto-alpha,beta-unsaturated esters occurs in a highly regioselective and enantioselective manner. The adducts could easily be converted into synthetically useful cyclohexenones, cyclohexanones, piperidines, and gamma-lactones.
