Herein, a direct C8-oxygenation of naphthalene derivatives is described. Different carbonyl groups were used as directing group to deliver corresponding naphthols via a palladium-catalyzed oxidation reaction using PhI(OAc)2 in a TFA/TFAA mixture. Interestingly, when Weinreb amide was employed as the directing group, the naphtholactone skeleton was directly obtained. This methodology was applied to
在此,描述了萘衍生物的直接 C8-氧化。使用不同的羰基作为导向基团,通过钯催化的氧化反应,在 TFA/TFAA 混合物中使用 PhI(OAc) 2来递送相应的萘酚。有趣的是,当采用 Weinreb 酰胺作为导向基团时,直接获得了萘内酯骨架。该方法用于合成各种取代的萘内酯。
