Abstract
O-Nitration reactions of betulin and trioxylupane under the action of a nitric acid and acetic anhydride mixture were studied, and effective approaches to the production of mono-, di-, and trinitroesters of the betulin series were developed. A one-stage method for the production of 2,3-seco-28-oxo-19β,28-epoxy-18a-oleane-2,3-dicarboxylic acid from betulin under the action of fuming nitric acid was proposed.
期刊介绍:
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
