β-enaminones has been developed. The elaborated methodology involves the cascade sequencing of carbonylative Sonogashira coupling of aryl iodide with a terminal alkyne and the oxidative dealkylation of tertiary amines. The efficient syntheses of β-enaminones were performed with a Pd/DNA catalyst, with NEt3, NPr3 and NBu3 used as amine sources. The catalyst was successfully recovered and used in several
已经开发出一种新的一锅法,可产生β-烯胺酮。详尽的方法学涉及芳基
碘与末端
炔烃的羰基化Sonogashira偶联的级联测序和叔胺的氧化脱烷基。使用Pd / DNA催化剂,以NEt 3,NPr 3和NBu 3为胺源,可以有效合成β-烯胺酮。该催化剂已成功回收,并用于随后的几个测试中,结果相同。提出了反应机理,总结了固定化的Pd NPs(
钯纳米颗粒)的活性。
