  • Title: Conjugate addition of allyl stannanes with concomitant triflation.
    Author: Beaulieu ED, Voss L, Trauner D.
    Journal: Org Lett; 2008 Mar 06; 10(5):869-72. PubMed ID: 18232702.
    Abstract:
    A new method for the conjugate addition of allyltributylstannane with concomitant triflation is described. This reaction works with functionalized enones, enals, enoates, and vinylogous esters. The resulting vinyl triflates can be used for intramolecular Heck reactions to afford the products of 5-exo-trig cyclization.
