摘要

The α-pyrones constitute an important class of biologically active compounds, and their synthesis has been a focus of considerable attention in synthetic organic chemistry 1 as well as in medicinal chemistry. 2 In the past decade, numerous methods reported for the synthesis of these structures utilize halolactonization or transition metals (Ag, Hg, Rh, Pd) to promote intramolecular addition of carboxylic acid to alkynes. 3 In general, these reactions of 4-alkynoic acids occur with ...
