Herein we report an advancement in the application of visible light photoredox catalysts in the oxidation of electron-rich arenes resulting in the selective deprotection of para-methoxybenzyl (PMB) ethers. This method is highlighted by excellent functional group tolerance, protecting group orthogonality, mild reaction conditions and avoidance of stoichiometric redox byproducts.
本文中,我们报道了在可见光光氧化还原催化剂在富电子芳烃氧化中应用的进展,从而导致对甲氧基苄基(PMB)醚的选择性脱保护。出色的官能团耐受性,保护基团正交性,温和的反应条件以及避免了化学计量的氧化还原副产物,从而突出了该方法。
