A novel application of highly stable Fe(OTf)3 as an efficient catalyst for the synthesis of a variety of β-enamino ketones and esters under solvent-free conditions is described. Notably, this protocol of a “green synthesis”, which produced β-enamino ketones and esters by the reaction of a variety of β-dicarbonyl compounds and primary amines, exhibits attractive properties including high yields, short
描述了一种高度稳定的Fe(OTf)3作为无催化剂条件下合成各种β-烯胺酮和酯的有效催化剂的新型应用。值得注意的是,这种“绿色合成”方案是通过多种β-二羰基化合物与伯胺的反应生成β-烯酮和酯,具有诱人的性能,包括高收率,较短的反应时间,较低的催化剂负载量和化学和区域选择性。另外,催化剂易于从反应系统中回收,并易于重新使用而活性损失最小。
