3-diacylpyrroles is reported that employs the direct use of N-acyl α-aminoaldehydes with 1,3-dicarbonyl compounds. The products were formed in up to 88% yield and shown to be hydrolytically and configurationally stable under the reaction conditions (THF/1,4-dioxane and H2O). The N-acyl α-aminoaldehydes were readily prepared from the corresponding α-amino acids. The reaction tolerates a wide array of substrate
据报道,直接使用N-酰基 α-
氨基醛与 1,3-二羰基化合物进行 Zr 催化合成四取代 1,3-二酰基
吡咯。产物的产率高达 88%,并且在反应条件(THF/1,4-
二恶烷和 H 2 O)下具有
水解稳定性和构型稳定性。N-酰基α-
氨基醛很容易由相应的
α-氨基酸制备。该反应可耐受多种底物类型,包括
氨基醛侧链上的烷基、芳基、杂芳基和含杂原子的基团。多种 1,3-二羰基被证明适合与衍生自l , l-二肽的醛一起反应,生成的醛原位,和N-酰化
葡萄糖胺。
