  • Title: Copper-catalyzed intramolecular tandem reaction of (2-halogenphenyl)(3-phenyloxiran-2-yl)methanones: synthesis of (Z)-aurones.
    Author: Weng Y, Chen Q, Su W.
    Journal: J Org Chem; 2014 May 02; 79(9):4218-24. PubMed ID: 24735197.
    Abstract:
    A convenient and efficient method for the copper-catalyzed synthesis of (Z)-aurones via intramolecular tandem reaction of (2-halogenphenyl)(3-phenyloxiran-2-yl)methanones is reported. Moreover, a plausible mechanism for the formation of (Z)-aurones is proposed. This is the first report on the synthesis of (Z)-aurones through copper-catalyzed Ullmann coupling reaction employing epoxides as substrates.
