With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1121-22-8,trans-Cyclohexane-1,2-diamine,as a common compound, the synthetic route is as follows.
General procedure: To a mortar were added 3,5-di-tert-butyl-2-hydroxybenzaldehyde (0.468 g, 2 mmol) and trans-cyclohexane-1,2-diamine (0.114 g,0.123 mL, 1 mmol), and these were mixed over 10 min. The product was recrystallized (CH2Cl2/EtOH 1:9) to give 1a as a bright yellow solid; yield: 0.487 g (89%).
1121-22-8, 1121-22-8 trans-Cyclohexane-1,2-diamine 43806, achiral-catalyst compound, is more and more widely used in various fields.
