preparation of fully substituted pyrroles, from readily accessible secondary propargylic alcohols, 1,3-dicarbonyl compounds and primary amines, has been developed. The one-pot multicomponent reaction, which is catalysed by the system [Ru(eta(3)-2-C(3)H(4)Me)(CO)(dppf)][SbF(6)]/CF(3)CO(2)H (dppf: 1,1'-bis(diphenylphosphanyl)ferrocene), involves initial propargylation of the 1,3-dicarbonyl compound promoted by
已经开发了一种简单高效的方法,该方法可从容易获得的仲炔丙醇,1,3-二羰基化合物和伯胺制备完全取代的吡咯。一锅多组分反应,由系统[Ru(eta(3)-2-C(3)H(4)Me)(CO)(dppf)] [SbF(6)] / CF(3)催化)CO(2)H(dppf:1,1'-双(二苯基膦基)二茂铁),涉及CF(3)CO(2)H促进的1,3-二羰基化合物的初始炔丙基化,以及随后生成的γ之间的缩合-酮炔和伯胺得到炔丙基化的β-烯氨基酯或酮,将其进行钌催化的5-exo-dig环化反应,形成最终的吡咯。
