What is Trans-(1R,2R)N,N'-Dimethyl-cyclohexane-1,2-diamine?
Description
Trans-(1R,2R)N,N'-Dimethyl-cyclohexane-1,2-diamine is a useful research chemical for organic synthesis and other chemical processes.
The Uses of Trans-(1R,2R)N,N'-Dimethyl-cyclohexane-1,2-diamine
trans-N,N′-dimethylcyclohexane-1,2-diamine can be used as a ligand in the synthesis of the following products via copper catalyzed C-N coupling reactions:
- vinylsulfoximines obtained from NH sulfoximes and vinyl bromides
- N-arylpyridones obtained via reaction between 2-substituted pyridines and aryl halides
- N-aryl amines obtained via reaction between amines and aryl iodides/aryl bromides
Synthesis
Cyclohexene oxide (1) was reacted with 25–30% aqueous methylamine (1.5 equiv.) in a sealed reactor to form trans-2-(methylamino)cyclohexanol 2 at 80 °C within 5h. Compound 2 was subjected to Mitsunobu reaction at room temperature, followed by adjusting the pH from 2 to 10 to yield 7-methyl-7-azabicyclo[4.1.0]-heptane 3, which was directly subjected to the following reaction without purification. Ring-opening reactions of compound 3 with a methylamine aqueous solution were completed in a sealed reactor at 110 °C after 6h to yield Trans-(1R,2R)N,N'-Dimethyl-cyclohexane-1,2-diamine.
