Preparation method of (1R,2R)-(-)-N,N'-dimethyl-1,2-cyclohexanediamine

The invention discloses a preparation method of (1R,2R)-(-)-N,N'-dimethyl-1,2-cyclohexanediamine. A methylation reaction of a cyclohexane compound represented by formula III and a methylation reagentis carried out in a solvent under the acation of an alkali to obtain a cyclohexane compound shown as a formula II. An amino group is protected through a benzoyl group, two methyl groups on the amino group can be avoided from being added at the same time, the methylation reaction condition is mild, benzoyl hydrolysis is easy, the danger that a large amount of lithium aluminum hydride is used is avoided, generation of solid waste is reduced, and environmental protection is facilitated. The method disclosed by the invention is low in cost, environment-friendly, high in reaction yield and suitablefor industrial safe mass production.

PRODUCTION METHOD OF TRANS-1,2 DIAMINOCYCLOHEXANE

PROBLEM TO BE SOLVED: To provide an industrial production method capable of efficiently producing trans-1,2-diaminocyclohexane from an isomer mixture of trans-1,2-diaminocyclohexane and cis-1,2-diaminocyclohexane. SOLUTION: In a production method of trans-1,2-diaminocyclohexane, an isomer mixture of 1,2-diaminocyclohexanes containing cis-1,2-diaminocyclohexane and trans-1,2-diaminocyclohexane reacts with a blocking agent reactive with an amino group to block two amino groups by a blocking group and is subjected to crystallization in the presence of a base to raise a trans/cis ratio in the isomer mixture of 1,2-diaminocyclohexanes.
