Selective ESIPT photocycloaddition of 3-hydroxyflavones with trans, trans-1,4-diphenyl-1,3-butadiene is described. Using this methodology, total syntheses of the natural products (±)-foveoglin A and (±)-perviridisin B have been accomplished. Enantioselective ESIPT photocycloaddition using TADDOLs as chiral hydrogen-bonding additives provided access to (+)-foveoglin A. Mechanistic studies have revealed the possibility for a photoinduced electron transfer (PET) pathway. Selective ESIPT photocycloaddition of 3-hydroxyflavones with trans,trans-1,4-diphenyl-1,3-butadiene has been achieved which enabled the total syntheses of isomeric aglain natural products foveoglin A and perviridisin B. Mechanistic studies have revealed the possibility of a photoinduced electron transfer (PET) pathway.
