[Synthesis of triterpene 2,6-dideoxy-alpha-L-arabino-hexopyranosides from L-rhamnal. Their pharmacological properties].

Triterpene 2,6-dideoxy-alpha-L-arabino-hexopyranosides were synthesized by the glycosylation of oleanane triterpene alcohols with L-rhamnal acetate in the presence of cationite KU-2-8 and lithium bromide. 2,6-Dideoxy-alpha-L-arabino-hexopyranosides of allobetulin and methyl glycyrrhetinate showed pronounced antiulcerous activity; the latter also stimulated reparative skin regeneration in rats and was effective as a hepatoprotectant.
