06 - 234Substituted Benzyl Ethers as Radical Stable Protecting Groups. —Various substituted benzyl ethers such as (I) are reacted with NBS in order tostudy their potential to serve as hydroxyl protecting groups with the ability towithstand radical bromination. The yields of the corresponding bromobenzoates(II) increase when benzyl ethers (I) contain electron-withdrawing substituents.— (LIOTTA, L. J.; DOMBI, K. L.; KELLEY, S. A.; TARGONTSIDIS, S.;MORIN, A.
