A series of enantiopure 2-azanorbornane-based amines were prepared via a stereoselective aza-Diels–Alder reaction and further modifications of the obtained cycloadduct. In particular, derivatives containing two bicyclic moieties linked by [Formula presented] fragments were synthesized. Two dimeric derivatives exhibited a significant antiproliferative activity against selected cell lines, comparable to cisplatin in certain cases.

We report the synthesis and preliminary evaluation of (1S,2S,4R)-7,7-dimethyl-1-phenylbicyclo[2.2.1]heptan-2-ol 1a, which was obtained in 3 steps from inexpensive starting materials, as a chiral auxiliary. The potential for asymmetric induction was investigated by carrying out aza-Diels-Alder reactions with cyclopentadiene and imine derivatives of 1a from (R)-(+)-1-phenylethylamine, (S)-(?)-1-phenylethylamine and benzylamine. The results showed marked exo selectivity and good diastereoisomeric excess when 1a was combined with (R)-(+)-1-phenylethylamine. These results are comparable with those reported using (?)-8-phenylmenthol, suggesting that 1a can represent an economically viable alternative to current chiral auxiliaries.

An enantiomerically pure diselenide containing two chiral bicyclic subunits was prepared from the respective halides. The stereochemical outcome of the reaction was established via NMR spectroscopy and X-ray diffraction measurements.
