A Tröger’s base derivative (5,12-dimethyl-3,10-diphenyl-1,3,4,8,10,11-hexaazatetracyclo [6.6.1.02,6.09,13]pentadeca-2(6),4,9(13),11-tetraenes) was used as an efficient catalyst for the three-component Mannich reactions of aromatic aldehydes and aromatic amines with ketones in water at room temperature. This rapid reaction afforded the corresponding β-amino ketones in good yields with excellent stereoselectivity
Tröger的基础衍生物(5,12-二甲基-3,10-二苯基-1,3,4,8,10,11-六氮杂四环[6.6.1.0 2,6 .0 9,13 ] pentadeca -2(6), 4,9(13),11-四烯)在室温下用作芳族醛和芳族胺与酮的三组分曼尼希反应的有效催化剂。该快速反应以良好的产率提供了具有优异的立体选择性的相应的β-氨基酮。
