Synthesis of polyphenols and azafluorenones

The synthesis of 1,3,4,5-tetragalloylapiitol was accomplished in 7 steps. A direct synthesis of natural and unnatural ellagitannins were made using an intramolecular oxidative coupling. Different flavonols were synthesized via a novel base-mediated cyclization step, which was strategically different than previous ways to make flavonols. A three step synthesis of azaflureones was developed
