The enantiopure iron complex 4 reacts under the influence of BF3·OEt2 with allylsilanes and enol acetates through a cationic intermediate in which the chirality of 4 is preserved, yielding enantiopure 5-substituted 3-pyrrolin-2-ones.
在 BF3Â-OEt2 的影响下,对映体铁络合物 4 与烯丙基硅烷和乙酸烯醇酯通过阳离子中间体发生反应,其中 4 的手性得以保留,从而生成对映体 5 取代的 3-吡咯啉-2-酮。
