A new approach for selective hydroxylation of non-activated cyclohexanes using dioxirane generated in situ in water through supramolecular control has been developed. Using β-CD and γ-CD as the supramolecular hosts, selective hydroxylation of cyclohexane substrates, including trans/cis-1,4-, 1,3-and 1,2-dimethylcyclohexanes and trans/cis-decahydronaphthalene, was achieved in up to 54% yield in water. Furthermore, site-selective C-H bond hydroxylation of (+)-menthol was achieved by obstructing the approach of dioxirane to the C-H bond with higher steric hindrance through inclusion complexation with β-CD and γ-CD in water.
Synthesis and structure-affinity relationships of 1,3,5-alkylsubstituted cyclohexylamines binding at NMDA receptor PCP site

A series of 1,3,5-alkylsubstituted cyclohexylamines 2 were synthesized as ligands for the N-methyl-D-aspartate (NMDA) receptor phencyclidine (PCP) binding site. Pure diastereomers with defined configuration of amino group 2- ax and 2-eq were obtained. The optimal size of 1,3,5-substituents was determined for cyclohexylamines 2 with an equatorial amino group in the lowest energy conformation using Hansch analysis. According to the data, the lipophilic part of cyclohexylamines 2 does not discriminate between hydrophobic regions of the PCP binding site but rather recognizes this site as a whole lipophilic pocket.

Unprecedented Stereoselectivity in the Addition of Organoiron(II) Reagents to Cyclohaxanone Derivatives
Reetz, Manfred T.,Stanchev, Stephan
, p. 328 - 330 (2007/10/02)
Various organoiron(II) reagents undergo Grignard-type additions to substituted cyclohexanone derivatives, C-C bond formation occurring stereoselectively from the equatorial direction (97 - 100percent selectivity).
