Epoxyolefin cyclizations have attracted considerable interest due to their importance in biosynthetic pathways. Bismuth trifluoromethanesulfonate as well as several other metal triflates are shown to be highly effective (0.1 mol %) catalysts for the cycli

The palladium catalyzed carbonylative cross-coupling reaction of indolylborates (2) with vinyl triflates (3) afforded indol-2-yl ketones (4), which were subsequently converted to hexahydroindeno[2,1-b]indoles (5) with the aid of an acid. This protocol was well adapted for the total synthesis of yuehchukene.

Nafion-H is shown to be an effective promoter of epoxide cyclizations to aromatic positions. The reactions can be done by passing a solution of the epoxide through a column packed with Nafion-H, or by stirring a mixture of the compound with the acidic pro
