  • Title: Highly chemo- and stereoselective palladium-catalyzed transfer semihydrogenation of internal alkynes affording cis-alkenes.
    Author: Li J, Hua R, Liu T.
    Journal: J Org Chem; 2010 May 07; 75(9):2966-70. PubMed ID: 20345142.
    Abstract:
    DMF (N,N-dimethylformamide)/KOH was found to be an efficient hydrogen source in the Pd(OAc)(2)-catalyzed transfer semihydrogenation of various functionalized internal alkynes to afford cis-alkenes in good to high yields with excellent chemo- and stereoselectivity. This catalytic process was also applied to the synthesis of analogues of combretastatin A-4.
