Regioselective Synthesis of 3-Alkynyl-5-bromo-2-pyrones via Pd-Catalyzed Couplings on 3,5-Dibromo-2-pyrone

Regioselective Synthesis of 3-Alkynyl-5-bromo-2-pyrones via Pd-Catalyzed Couplings on 3,5-Dibromo-2-pyrone

3,5-Dibromo-2-pyrone underwent facile Pd(0)-catalyzed coupling reactions with various alkynes to give rise to the corresponding 3-alkynyl-5-bromo-2-pyrones with good to excellent chemical yields and regioselectivity.
