Abstract

The application of intramolecular enone-olefin photo- cycloadditions to the synthesis of natural products has re- ceived much attention over the years.1 Recently, a photocy- cloaddition was employed in the synthesis of hetisine alka- loids and functionalized 5-8-5 ring systems.2 Fusoxysporone was first isolated from liquid cultures of the fungus Fusarium oxysporum3 in 1992. Fusarium oxysporum is an economi- cally important soilborne plant pathogen and to date over 120 formae ...
