A convenient Rh(III)-catalyzed C-H activation and cascade [4+2] annulation for the synthesis of naphthalenone sulfoxonium ylides has been developed. This method features perfect regioselectivity, mild and redox-neutral reaction conditions, and broad substrate tolerance with good to excellent yields. Preliminary mechanistic experiments were conducted and a plausible reaction mechanism was proposed.
已经开发了一种方便的 Rh(III) 催化的 CH 活化和级联 [4+2] 环化,用于合成萘酮锍叶立德。该方法具有完美的区域选择性、温和且氧化还原中性的反应条件以及广泛的底物耐受性和良好的收率。进行了初步的机理实验,并提出了一个合理的反应机理。新型萘酮锍叶立德可以进一步转化为多取代萘酚,这证明了该方法的实用性。
