Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1436-59-5, Name is cis-Cyclohexane-1,2-diamine, Formula: C6H14N2.

The potent and selective cyclin-dependent kinase 2 (CDK2) inhibitor NU6027 (6-cyclohexylmethoxy-5-nitroso-2,4-diaminopyrimidine) was used as the lead for the synthesis of a series of analogues in order to provide further insight into the structure?activity relationships for 2,4-diaminopyrimidine CDK2 inhibitors. Aliphatic amino substituents were introduced at position 2. The use of linear or less sterically hindered amines gave rise to compounds endowed with slightly better activity than the lead; on the other hand, the compounds were less active if a bulkier amino substituent was used. Substitution of the 5-nitroso group with a 5-cyano-NNO-azoxy moiety afforded a new class of inhibitors, the activity of which against CDK2 was found to be similar to that of the nitroso series. The most active nitroso compound was 8 b ((2S)-2-[(4-amino-6-cyclohexylmethoxy-5-nitrosopyrimidin-2-yl)amino]propan-1-ol; IC50=0.16 mum), while in the 5-cyano-NNO-azoxy series the most active compound was 9 b (4-amino-5-[(Z)-cyano-NNO-azoxy]-2-{[(2S)-1-hydroxypropan-2-yl]amino}-6-cyclohexylmethoxypyrimidine; IC50=0.30 mum). Taken together, these new analogues of NU6027 enhance our understanding of the structure?activity relationships for 2,4-diaminopyrimidine CDK2 inhibitors.

The reaction of (NH4)2[WS4] with (±)trans-1,2-diaminocyclohexane (trans-1,2-cn), bis(2-aminoethyl)amine (dien) and bis(3-aminopropyl)amine (dipn) leads to the formation of the organic ammonium tetrathiotungstates (trans-1,2-cnH)2[WS4] (1), (dienH2)[WS4] (2) and (dipnH2)[WS4] (3) [trans-1,2-cnH is (±)trans-2-aminocyclohexylammonium; dienH2 is 1,7-diazonia-4-aza-heptane; dipnH2 is 1,5-diazonia-9-aza-nonane] in good yields. The title complexes 1-3 react with [Ni(en)3]2+ (en = ethylenediamine) forming the highly insoluble complex [Ni(en)3][WS4]. The structure of the complexes 1-3 can be described as consisting of tetrahedral [WS4]2- dianions which are linked to the monoprotonated cation of trans-1,2-cn in 1 and the diprotonated cations of dien and dipn in 2 and 3, with the aid of weak hydrogen bonding interactions. The difference between the longest and the shortest W-S bond lengths Delta is 0.0104, 0.0170 and 0.0173 A? in 1, 2 and 3, respectively. A comparative study of the structural features of several tetrathiotungstates is presented and the interactions between the organic cations and the tetrathiotungstate anions are discussed in terms of the magnitude of Delta, the difference between the longest and the shortest W-S bond distances.

We have investigated the mechanosynthesis of a series of second-sphere salts, guest?[H2L]2+·[MCl4]2? [L = N,N?-dibenzyl-(±)-trans-1,2-diaminocyclohexane], and the reversible transformations to their chelating coordination complexes [MCl2(L)] through dehydrochlorination reactions.

A chiral gelator, RR- or SS-N,N?-diperfluorooctanoyl-1,2- diaminocyclohexane, gelated racemic 2-butanol. The gel was most stable at the racemic mixture, its stability lowered with the increase in the optical purity of the gelator. Notably, characteristic helically coiled fibrils were formed in the narrow region of enantiomer excess (ee = 0.2-0.4). Promotion effects of the antipodal enantiomers are proposed.

Reaction of 2,5-dihydroxybenzaldehyde with 0.5 equivalent of 1,2-diaminoethane, trans-1,2-diaminocyclohexane or 1,2-diaminobenzene in the absence or presence of hydrated Cu(O2CMe)2·H2O in refluxing MeOH respectively afforded the ligands H2L and complexes [Cu(L)] [H2L = N,N?-bis(2,5-dihydroxybenzylidene)-1,2-diaminoethane (H2L1), N,N?-bis(2,5-dihydroxybenzylidene)-trans-1,2-diaminocyclohexane (H2L2), N,N?-bis(2,5-dihydroxybenzylidene)-1,2-diaminobenzene (H2L3)] in yields of 66-86%. Using X- and Q-band EPR and 1H and 14N X-band ENDOR data, the following fractional unpaired spin densities were calculated: rho{Cu} = 0.75, rho{N} = 0.07, rho{O} ? 0.04, rho{H} = 0.01. Density functional (DF), intermediate neglect of differential overlap with spectroscopic parameterisation (INDO/S) and extended Hueckel calculations of [Cu(MeOsalen)] broadly reproduced these results, the DF calculations demonstrating that the phenoxide oxygen lone pair is misdirected away from the Cu-O bond. The cyclic voltammograms of the ligands and complexes in dmf-0.1 M NBun4PF6 at 293 K showed a single oxidation of the two ligand hydroquinone groups, and two principal daughter processes: an irreversible reduction of the initial oxidised quinone, probably in a monoprotonated or metallated form; and a more cathodic reduction and associated reoxidation indicative of a proton- and metal ion-induced electrochemical step-chemical step-electrochemical step reaction.

Even if (±)-trans-1,2-diaminocyclohexane crystallizes as a conglomerate, its low melting point (-10 C) and its sensitivity to light, CO2, O2, and moisture make this molecule difficult to resolve. It has been shown that the citrate monohydrate of this compound crystallizes as a stable conglomerate with a high thermal stability (up to 163 C) with no drawbacks as to those listed above for the pure diamine. The crystal structure of this salt, resolved by single crystal X-ray diffraction, reveals structural features consistent with the thermal stability of this phase. Several preferential crystallization attempts (AS3PC) have been performed at a 100 ml scale and at a one liter scale in water with and without additives. Finally a productivity of 40 g per batch per liter of solvent per hour was achieved with a crude enantiomeric purity better than 90%. A simple recrystallization of the crude crops gives quantitatively the crystalline compound with an ee >99% proving the absence of partial solid solution at room temperature.
