The acid-catalyzed rearrangement of triterpenoid monoenes belonging to the hopane and migrated hopane series with sulfuric acid and boron trifluoride etherate was investigated.By selecting the reaction conditions, a variety of the monoenes of these series, including three new compounds, 9βH-fern-7-ene (3c), 8βH-fern-9(11)-ene (4b), and adian-5(10)-ene (5b), were obtained.For comparison, oleanenes and migrated oleanenes were also subjected to the same reaction.Keywords--acid-induced rearrangement; triterpenoid hydrocarbon; hopane, migrated hopane; 9βH-fern-7-ene; 8βH-fern-9(11)-ene; adian-5(10)-ene; sulfuric acid; boron trifluoride
