1121-22-8, trans-Cyclohexane-1,2-diamine is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Paraformaldehyde (0.32 g) was mixed with N,N-dimethylformamide (1.92 g) and heated to 80 C to make a slurry. (¡À)-trans-1,2-Cyclohexanediamine (2) (Aldrich 270016) (0.53 g) was added to the slurry, where upon the mixture turned orange. The mixture was heated for 0.5 h at 80 C, then cooled and left for one week. The mixture was filtered and the crystals washed with ethanol to afford the 1,8,10,17-tetraazapentacyclo[8.8.1.18,17.02,7.011,16]icosane (4) (0.46 g; 71%). The product was recrystalised from a mixture of 1 part petroleum ether, 2 parts hexanes and 1.3 parts ethyl acetate (by volume; total volume 21.5 mL). Insoluble material was removed by filtration and the filtrate left to crystallize to afford off-white prisms (67% recovery), m.p. 210 C., 1121-22-8
1121-22-8 trans-Cyclohexane-1,2-diamine 43806, achiral-catalyst compound, is more and more widely used in various fields.
