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: Aldehyde (2.2 mmol, salicylaldehyde or 4-methoxysalicylaldehyde, 4-diethylamino-2-hydroxy benzaldehyde or 2,4-dihydroxybenzaldehyde) was dissolved in ethanol (30 ml) and stirred at room temperature. To this solution, either ethylene diamine (1 mmol) or trans-1,2-diaminocyclohexane (1 mmol) was added drop-wise under stirring. The immediate appearance of yellow colour indicates the formation of Schiff bases. The solution was allowed to stir for another 6 h at room temperature that produced yellow to light yellow coloured precipitates. The formed precipitate was filtered off, washed with ethanol and dried under vacuum.

1121-22-8, 1121-22-8 trans-Cyclohexane-1,2-diamine 43806, achiral-catalyst compound, is more and more widely used in various fields.
