Beschreibung

Allgemeine Beschreibung

(R,R)-(-)-N,N′-Dimethyl-1,2-cyclohexanediamine is a N,N′-dimethylated derivative of enantiopure 1,2-diaminocyclohexane. It can be formed during the hydrolysis of (R_3a,R_7a)-1,3-(dimethyl)-2-phenyl-2,3,3a,4,5,6,7,7a-octahydro-1H-1,3,2-benzodiazaphosphole 2-oxide using HCl-methanol.

Anwendung

(R,R)-(−)-N,N′-Dimethyl-1,2-cyclohexanediamine can be used:

• As a ligand in the preparation of 4H-benzo[f]imidazo[1,4]diazepin-6-one through multi-component Ullmann coupling reaction.
• In one of the key synthetic steps for the preparation of tricyclic γ-secretase modulators.
• To prepare chiral fluorous diamino-diol proligand, which is used in the synthesis of zirconium metal complexes applicable as catalysts in 1-hexene polymerization.
