Efficient synthesis of 2-naphthols was realized by Ru(II)-catalyzed C–H activation of aryl nitrones and intermolecular [3+3] annulation with α-diazo sulfonyl ketones under redox-neutral conditions. Easily available α-diazo sulfonyl ketones act as a three-carbon component in the reaction.
通过Ru(II)催化的芳基硝酮的C–H活化和在氧化还原中性条件下用α-重氮磺酰基酮进行分子间[3 + 3]环化,可以实现
2-萘酚的高效合成。容易获得的α-重氮磺酰基酮在反应中充当三碳组分。
