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.

Zeolite-supported sodium azide reagents are versatile catalysts for the conversion of various alkenes and alcohols to the corresponding azides in good yield under mild conditions.
IMINOPHOSPHORANE-MEDIATED TRANSFORMATION OF TERTIARY ALCOHOLS INTO t-ALKYLAMINES AND THEIR N-PHOSPHORYLATED DERIVATIVES

Novel azidation of tertiary alcohols by means of trimetylsilyl azide in the presence of boron trifluoride etherate has been worked out.The Staudinger reaction of crude azides with triethyl phosphite affords the corresponding iminophosphoranes which can be directly transformed into diethyl N-(t-alkyl)phosphoroamidates or t-alkylamine tosylates.
