A cationic Pd(II)-catalyzed reductive cyclization of alkyne-tethered ketones or aldehydes using ethanol as hydrogen source under mild conditions was developed. The reaction is an environmentally benign synthetic method and proceeds efficiently to give useful N-heterocycles or carbocycles bearing an exocyclic double bond and a hydroxyl group in high yield.
在温和条件下,使用乙醇作为氢源,开发了阳离子Pd(II)催化炔烃系酮或醛的还原环化反应。该反应是对环境无害的合成方法,并有效地进行,以高收率得到有用的带有杂环外双键和羟基的N-杂环或碳环。
