摘要:
为了探究Brich还原反应的影响因素,分别以 1,6-二甲氧基萘、 2,7-二甲氧基萘、 1,7-二甲氧基萘、 2,6-二甲氧基萘为底物,反应得到相应的二氢化萘衍生物,随后加入质子酸水解、亚硫酸氢钠溶液提纯,成功合成出4种对应萘满酮结构,其收率分别为 84.3%、 81.7%、 83.4%、 80.2%,邻位取代收率优于间位取代,同时以后面两种甲氧基萘为底物合成相应萘满酮为首次报道。与相关文献对比发现,苯环侧取代基的数量及类型对于收率有一定的影响,苯环上取代基数量越多,反应收率反而越低;取代基结构越稳定,反应收率越高,其中取代基为烷烃时,碳链越长,收率越低。
Abstract:
To explore the influencing factors of the Brich reduction reaction, the corresponding dihydronaphthanlene derivatives with methoxy were prepared from 1,6-dimethoxynaphthalene, 2,7-dimethoxynaphthalene, 1,7-dimethoxynaphthalene, and 2,6-dimethoxynaphthalene, respectively. Afterward four corresponding tetralone structures were synthesized by acid hydrolysis and purification with sodium bisulfite from dihydronaphthanlene derivatives, and their yields were 84.3%, 81.7%, 83.4%, 80.2%, respectively. Through the above experiments, it is found that the yield from naphthalene derivative with ortho substitution is higher than that with meta substitution. And it is the first report that the two corresponding tetralones were synthesized from 1,7-dimethoxynaphthalene, and 2,6-dimethoxynaphthalene. Compared with the literatures, the number and stability of substituents on the benzene ring have a great impact on the yield, the yield from substrate with multiple substituents is lower than that from monosubstituted substrate; and the yield from substrate with highly stable substituent is higher than that with weakly stable substituent, in which long chain alkane is used as a substituent, the yield decreases with the increase of the carbon chain.
