(Equation presented) A barrelene derivative fragments to afford benzene and trappable 1,2,3-tricyanocyclopropene. The barrelene anion fragments more easily to liberate benzene and the 1,2,3-tricyanocyclopropenyl anion, which is not trappable or stable in solution. However, the major thermal product from the barrelene anion is a rearranged allyl anion that is formed by disrotatory cleavage of the cyclopropyl ring, a formally Woodward-Hoffmann-forbidden process. Several proposals are offered to rationalize this forbidden rearrangement.

The Diels-Alder product 1b, of tosylacetylene and N-tert-Boc-pyrrole, was converted into (+/-)-conduramine C-1 (22) and the tetraacetates of (+/-)-conduramine A-1 (9b) and F-1 (15b).
