Disclosed herein is a rhodium(III)-catalyzed intramolecular cyclization of ynamides with propargyl esters. A variety of highly functionalized 2,5-dihydropyrroles were obtained in moderate to good yields with high E/Z selectivities. Subsequent oxidation of the products gave valuable pyrrole derivatives. Additionally, scale-up reactions and late-stage derivatizations highlight the potential synthetic
本文公开了铑(III)催化的炔酰胺与炔丙酯的分子内环化。以中等至良好的收率和高E / Z选择性获得了多种高度官能化的 2,5-二氢吡咯。随后的产物氧化得到有价值的吡咯衍生物。此外,放大反应和后期衍生化凸显了该方法的潜在合成效用。
