molecules. We have developed a new 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDCI)-mediated oxazolerearrangement that affords quaternary 5,5-(aryl, allyl)-substituted hydantoins found in many biologically significant compounds. Furthermore, these quaternary hydantoins can be chemically manipulated to yield the corresponding quaternary imidazolones, which is a unique scaffold found
