  • Title: Unexpected formation of (E)-4-alkene 1,3-diketones from the three-component reaction of lithium selenolates with 1-(1-alkynyl)cyclopropyl ketones and aldehydes.

    Journal: J Org Chem; 2011 Jul 15; 76(14):5598-605. PubMed ID: 21615137.
    Abstract:
    A novel three-component stereoselective synthesis of (E)-4-alkene 1,3-diketones from lithium selenolates, 1-(1-alkynyl)cyclopropyl ketones, and aldehydes is reported. This reaction afforded the products in moderate to good yields with the formation of a new C-Se single bond, a new C-C double bond, and a new C-O double bond.
