the title compounds involves a tandem process including allenyne [2+2] cycloaddition, radical addition onto the in situ formed cyclobutenyl moiety followed by radical coupling/oxidation. Interestingly, different kinds of functionalized naphthalene derivatives could be obtained selectively from the same substrates, and the selectivity was easily controlled by finely tuning the reaction conditions.
通过苯连接的烯炔与亚硝酸叔丁酯的级联反应,提出了一种新颖的环丁醇稠合的2-硝基萘-1-醇和硝基环丁烷稠合的萘1,2-二酮的合成方法。标题化合物的形成涉及串联过程,包括烯丙炔[2 + 2]环加成,自由基加成到原位形成的环丁烯基部分上,然后进行自由基偶联/氧化。有趣的是,可以从相同的底物上选择性地获得不同种类的官能化萘衍生物,并且通过微调反应条件可以容易地控制选择性。
