3-Aryl-4-hydroxytetrahydroisoquinolines have been prepared from deoxybenzoins. The nitrosation of the latter derivatives has been improved and the catalytic reduction of the obtained oximinoketones has been carried out with the help of ultrasounds. Heterocyclization to the isoquinoline moiety occurred on the unprotected 1,2-aminoalcohol to give stereoselectively the corresponding hydroxylated heterocycle

the system Al2O3/R2NH to give β-aminoketones. The latter tandem amination system has also been applied in the Mannichreaction, improving the synthesis of several new diaryl β-aminoketones. Besides, the sequential use of DMFDMA and LAH-CuI on deoxybenzoins furnishes a newroute 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。
