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.
开发了一种高效的铑(III)催化的炔烃与丙烯酸直接氧化环化反应,形成α-吡喃酮。在此转化过程中,各种取代的丙烯酸是相容的,在温和的条件下以中等至极好的收率提供了相应的产物。
