La. Baltina et al., THE SYNTHESIS OF TRITERPENE 2-DEOXY-ALPHA -D-HEXOPYRANOSIDES FROM GLYCALS AND THEIR EFFECT ON REPARATIVE PROCESSES, Bioorganiceskaa himia, 23(6), 1997, pp. 512-518
Triterpene 2-deoxy-alpha-D-hexopyranosides were synthesized by the gly
cosylation of oleanane triterpene alcohols with D-glucal and D-galacta
l acetates in the presence of di(sym-collidine)iodonium perchlorate wi
th subsequent deiodination and deacetylation of the resulting 2-deoxy-
2-iodo-alpha-D-glycosides. 2-Deoxy-alpha-D-arabino- and -lyxo-hexopyra
nosides of methyl glycyrrhetinate demonstrated pronounced antiulcer ac
tivity and stimulated reparative skin regeneration in rats more effect
ively than glycyrrhizic acid and methyluracil.
