Furans and pyrroles are prepared from 1-alkynes by using a Cu(II)-promoted, one-pot, microwave irradiation method. Glaser coupling of 1-alkynes and cyclization of the resulting 1,3-diyne in the presence of an anhydride or a primary amine results in the formation of the respective 2,5-diaryl- or 2,5-dialkyl-substituted furans and pyrroles.
呋喃和吡咯是通过使用Cu(II)促进的一锅微波辐射法从1-炔烃制得的。在酸酐或伯胺存在下,1-炔的Glaser偶联和所得1,3-二炔的环化反应分别形成2,5-二芳基或2,5-二烷基取代的呋喃和吡咯。
