Part I: Intramolecular [2+2] photocycloaddition - fragmentation:facile entry to the tricyclic 5-6-7 fusoxysporone ring system
An expeditionary route to the tricyclic core of fusoxysporone is described. The chemistry capitalized upon both exantioselective glyoxylate-ene reaction and [2+2] photocycloaddition-fragmentation stratagem.
Part II: Synthesis of Erybraedins C
The titanium-catalyzed reaction of various 2H-chromenes and 2-alkoxy-1,4-benzoquinones stereoselectively yielded [2+3] adduct. Thus, conversion of palladium-catalyzed coupling gave final product.
