Betulin 3,28-di-O-tosylate
The title compound, C44H62O6S2 {systematic name: (1R,3aS,5aR,5bR,7aR,9S,11aR,11bR,13aR,13bR)-5a,5b,8,8,11a-penta-methyl-1-(prop-1-en-2-yl)-3a-[(tos-yloxy)meth-yl]icosa-hydro-1H-cyclo-penta-[a]chrysen-9-yl 4-methyl-benzene-sulfonate}, was obtained by tosyl-ation of naturally occurring betulin. All the cyclo-hexane rings adopt chair conformations and the cyclo-pentane ring adopts a twisted envelo...
متن کاملDerivatisation of Betulin for industrial applications
Research and development of renewable resources are highly relevant today because of the limited supply of oil and its emission of greenhouse gases. New sustainable material has to be found and the idea of this project is to investigate and create possible conditions for a polymer made of the renewable resource betulin. Betulin is a naturally occurring triterpene in birch bark. A combination of...
متن کاملCarbon Dioxide Adsorption in Betulin-Based Micro- and Macroporous Polyurethanes
Microporous polymers, that is polymers having pores of molecular size (D<2 nm), attracted a lot of interest during the last few years. They are promising materials for gas storage or separation but could also find use in heterogeneous catalysis. Recently, the separation of the green house gas CO2 evoked large interest in the scientific community. Among other microporous materials, such as activ...
متن کاملBetulin Phosphonates; Synthesis, Structure, and Cytotoxic Activity.
Betulin derivatives are a widely studied group of compounds of natural origin due to their wide spectrum of biological activities. This paper describes new betulin derivatives, containing a phosphonate group. The allyl-vinyl isomerization and synthesis of acetylenic derivatives have been reported. Structural identification of products as E and Z isomers has been carried out using ¹H-, (13)C-, (...
متن کاملBiotransformation of Cyclodextrine-Complexed Semisynthetic Betulin Derivatives by Plant Cells.
In this study, three semisynthetic betulonic acid-based compounds, 20(29)-dihydrolup-2-en[2,3-d]isoxazol-28-oic acid, 1-betulonoylpyrrolidine, and lupa-2,20(29)-dieno[2,3-b]pyrazin-28-oic acid, were studied in biotransformation experiments using Nicotiana tabacum and Catharanthus roseus cell suspension cultures. Biotransformation was performed using cyclodextrin to aid dissolving poorly water-s...
