(1R,2S)-N,N'-Bis[(E)-1H-pyrrol-2-yl-methyl-idene]cyclo-hexane-1,2-diamine monohydrate.

ABSTRACT: The title compound, C16H20N4·H2O, was synthesized from cis-1,2-diamino-cyclo-hexane (a racemic mixture of the (1R,2S) and (1S,2R) enanti-omers). The compound crystallized with two mol-ecules (A and B) in the asymmetric unit with a single water solvent mol-ecule per Schiff base mol-ecule. Mol-ecules A and B have similar conformations as illustrated by the least-squares-fit with an r.m.s. deviation of 0.242 Å. The mol-ecules within the asymmetric unit are bridged by hydrogen bonds to the two water mol-ecules, resulting in a heterotetramer. The water mol-ecule acts as both a hydrogen-bond donor and acceptor. The pyrrole-imine units are not co-planar, making an angle of 73.9 (3)° and 76.9 (3)° in mol-ecules A and B, respectively.

(1R,2R)-N,N'-Dimethyl-cyclo-hexane-1,2-diamine.

Project description:The molecule of the title compound, C(8)H(18)N(2), possesses C(2) symmetry. Owing to its stereochemistry, it is used in the synthesis of chiral ligands and metal complexes for asymmetric synthesis. The cyclo-hexane ring shows a chair conformation with the amino groups in equatorial positions. Contrary to the literature, the title compound is not a liquid, but a crystalline solid at room temperature (293 K). The absolute configuration is assigned from the synthesis.

(1R,2R)-N,N'-Diisobutyl-N,N'-dimethyl-cyclo-hexane-1,2-diamine.

Project description:The title compound, C(16)H(34)N(2), is a chiral diamine with fixed R configuration at both stereogenic carbon centres of the cyclo-hexane backbone. Due to their different substituents, the two N atoms also become stereogenic. In the crystal structure, the configuration at one of the two nitro-gen centres is fixed, with the free electron pair pointing inward and the isobutyl group in a trans position towards the cyclo-hexane backbone resulting in an R configuration. The isobutyl group at the second N atom, however, is disordered with 75% S configuration and 25% R configuration. In both cases, the isobutyl group is arranged in a trans position towards the cyclo-hexane backbone.
