carried out in the presence of an acid additive, on the other hand, 4‐acyl‐1‐naphthol was formed through ring opening of the spiroindanedione moiety attacked by the in situ released dimethylamine. In addition, the reactions are suitable for gram‐scale applications and compatible with a variety of substrates. Moreover, the naphthol products allow structural elaborations and hybridization with clinic drug
本文提出了通过芳基烯胺酮与重氮茚满二酮的条件控制发散级联反应,可切换合成萘酮螺茚满二酮或4-酰基-1-萘酚。当反应在氧化添加剂存在下进行时,萘酮螺茚满二酮通过 C(sp2)-H 烷基化形成,然后同时螺环化和二甲胺消除。另一方面,当反应在酸添加剂存在下进行时,4-酰基-1-萘酚是通过原位释放的二甲胺攻击的螺茚满二酮部分开环形成的。此外,该反应适合克级应用并与多种底物兼容。此外,萘酚产品可以进行结构精制并与临床药物杂交,从而进一步提高了该开发方法的价值。
