A number of compounds with a substituted hexahydro-2H-4,6-(epoxymethano)chromen8(5H)-one framework was synthesized starting from monoterpenoid (–)-verbenone and aromatic aldehydes containing methoxy and hydroxy groups. Cytotoxic activity of these compounds on human tumor cell lines was studied for the first time. Compounds containing three methoxy groups in each aromatic ring were found to be the most promising for further studies.

Lipid components of the seeds ofViburnum opulus (Caprifoliaceae family) were investigated. The neutral lipids consist of eight classes, the glycolipids consist of three classes, and the phospholipids contain seven classes. The fatty-acid contents of all of the acyl-containing lipids were determined. The 18∶2 fatty acid is the main component of all the lipid fractions. The content of saturated acids is greater in the glycolipids and phospholipids. The lipophilic components, higher fatty alcohols and sterols, were identified.

A synthetic route to 1-hydroxy- and 1-alkoxymethyl-3-polyfluoroalkylpyrazoles via regioselective N-hydroxy- and alkoxymethylation of N-unsubstituted pyrazoles with paraformaldehyde has been proposed. The alkoxyalkylation of polyfluoroalkylpyrazoles proceeds in aqueous-alcohol medium, whereas hydroxymethylation requires anhydrous conditions.

We synthesized the cis-3- and 4-methyl-2-oxo-6-(σ-carboxybutyl) hexahydro [3,4-d]-imidazoles by the reduction of the 3- and 4-methyl-2-oxo-2,3-dihydro-6-(carboxybutyl)-1H-thieno [3,4-d] imidazoles with HSiEt3 in CF3COOH and subsequent alkaline hydrolysis of the intermediate methyl ethers.

The reactions of ethyl methylsulfonylpyruvate and its sodium salt with a mixture of aromatic aldehyde and arylamine afforded 1,5-diaryl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-ones. The spatial structure of 1,5-diphenyl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-one was established by X-ray diffraction analysis.
