  • Title: N-heterocyclic carbene-catalyzed internal redox reaction of alkynals: an efficient synthesis of allenoates.
    Author: Zhao YM, Tam Y, Wang YJ, Li Z, Sun J.
    Journal: Org Lett; 2012 Mar 16; 14(6):1398-401. PubMed ID: 22352302.
    Abstract:
    An efficient N-heterocyclic carbene (NHC)-catalyzed internal redox reaction of alkynals that bear a γ leaving group has been developed. This process provides a new access to a range of allenoates in good yields. Preliminary results demonstrate that the enantioselective variant can also be achieved.
