The rhodium-catalyzed intramolecular hydroaminomethylation reaction, generating 4-aryl-2,3-dihydropyrroles, has been developed. Triphenylphosphine has been proved to be the excellent ligand to prepare the dihydropyrrole derivatives in up to 99% yield. This procedure provides an efficient and simple alternative route to synthesize 4-aryl-2,3-dihydropyrrole derivatives only in one step.
已开发出铑催化的分子内氢氨基甲基化反应,生成4-芳基-2,3-二氢吡咯。三苯基膦已被证明是制备二氢吡咯衍生物的优良配体,产率高达99%。该方法提供了仅一步即可合成4-芳基-2,3-二氢吡咯衍生物的有效且简单的替代途径。
