A one-pot, consecutive, four-component synthesis of 5-acylpyrid-2-ones initiated by Pd/cataCXium® ABn catalysis proceeds under mild reaction conditions and in good yields, with a broad scope of three points of diversity. This sequence is superior to the initially proposed Pd/Cu-catalyzed version because all four components can be employed in close to stoichiometric amounts.
由 Pd/cataCXium® ABn 催化引发的 5-acylpyrid-2-one 的一锅、连续、四组分合成在温和的反应条件下以良好的收率进行,具有广泛的三点多样性。该序列优于最初提出的 Pd/Cu 催化版本,因为所有四种组分都可以以接近化学计量的量使用。
