the system Al2O3/R2NH to give β-aminoketones. The latter tandem amination system has also been applied in the Mannich reaction, improving the synthesis of several new diaryl β-aminoketones. Besides, the sequential use of DMFDMA and LAH-CuI on deoxybenzoins furnishes a new route for the synthesis of enones.
制备了烯胺酮并使其与
LAH和Al 2 O 3 / R 2 NH体系共轭还原,得到β-
氨基酮。后者的串
联胺化系统也已用于曼尼希反应中,从而改善了几种新的二芳基β-
氨基酮的合成。此外,
DMFDMA和
LAH-CuI在脱氧
安息香素上的顺序使用为烯酮的合成提供了一条新途径。
