Rhodium(III)‐Catalyzed Oxidative Annulation of Acrylic Acid with Alkynes: An Easy Approach to the Synthesis of α‐Pyrones

A highly efficient rhodium(III)‐catalyzed direct oxidative annulation of acrylic acid with alkynes to form α‐pyrones was developed. Various substituted acrylic acids were compatible in this transformation, affording the corresponding products in moderate to excellent yields under mild conditions. Py...
