New oleanane alcohols and their acetates were prepared using classical reductive reagents (LiAlH4, NaBH4, and B2H6-DMS). In this research, we also studied the influence of these reagents on the stereoselectivity of reduction. All compounds prepared w

The two previously unreported esters 1 and 2 of pentane-2,4-diol and p-coumaric acid (=3-(4-hydroxyphenyl)prop-2-enoic acid) along with 13 known compounds including 6 oleanane- and ursane-type triterpenoids were isolated from MeOH extracts of the ste

The reactions of selected triterpenic oxo compounds with Lawesson's reagent were investigated. We examined sulfurization of some oxygen compounds and for these reactions several hindered ketones, one aldehyde, α-hydroxyketones, esters, or anhydrides

A series of Ni(OEtHex)2/phosphine/Et2AlCl systems were used as cycloisomerization catalysts of various 1,6-heptadienes. The best results were obtained with the catalytic system using triphenylphosphine as a ligand. The cycloisomerization with this sy
