A convenient preparative method is developed allowing for expeditious assembly of 3,5-diarylsubstituted 5-hydroxy-1,5-dihydro-2H-pyrrol-2-ones from routinely available inexpensive synthetic precursors. These compounds could not be prepared via the previously known protocols, as 2-aminofuran derivatives were produced instead.
                                    开发了一种方便的制备方法,允许从常规可用的廉价合成前体快速组装 3,5-二芳基取代的 5-羟基-1,5-二氢-
2H-吡咯-2-酮。这些化合物无法通过先前已知的方案制备,而是生产 2-
氨基
