AB  - The stereodivergent synthesis of two hyacinthacine analogues, which relies on an organocatalyzed aldol addition, is described. The aldol addition of dioxanone to an -N-carbobenzyloxy-substituted chiral aldehyde, promoted by both (R)- and (S)-proline, proceeds in reasonable yields with acceptable diastereomeric ratios. The success of the reaction may be due to the use of an acyclic aldehyde acceptor, which allows reagent control of the stereochemical outcome of the key aldolization step in both the matched and mismatched cases.

AB  - Reductive debromination of endo-(+)-3-bromocamphor with different primary amines followed by imine formation was investigated. This reaction requires simple experimental procedure without any organic solvent, metal or conventional reducing agent. A strong influence of amine polarity on the efficacy of debromination process was observed, and ethanolamine and ethylene diamine having sufficiently high boiling points can debrominate 3-bromocamphor giving corresponding camphanimines in good isolated yields. The mechanisms of debromination of 3-bromocamphor with ethanolamine and n-hexylamine were investigated at the B3LYP/6-311+G(d,p) level of theory. The radical mechanism was revealed, and it was shown that the reaction with more polar ethanolamine is energetically more favorable.

AB  - Two novel cadmium(II) complexes with condensation derivatives of 2-acetylpyridine or 2,6-diacetylpyridine with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of the complexes revealed a bidentate coordination of the 2-acetylpyridine derivative, while the symmetric 2,6-diacetylpyridine derivative was coordinated tridentately. It was found that the oxygen atoms were not coordinated to the cadmium ions, despite the fact that they are the position to form six membered chelate rings. NMR spectroscopy investigations showed that the coordination properties of the ligands do not change in solution. Both complexes possess cytotoxic potential, as determined by the toxicity test to Artemia
