1,5-Dihydroxynaphthalene is a versatile Ï-electron rich aromatic ring system which has been employed widely for the construction of mechanically-interlocked molecular compounds and supramolecular complexes. A much-needed procedure for its transformation into 1-benzyloxy-5-hydroxynaphthalene has been developed. It involves (i) bisacetylation of 1,5-dihydroxynaphthalene, (ii) reductive removal of one of the two acetyl groups, (iii) benzylation, and (iv) cleavage of the remaining acetyl group.
1,5-二羟基萘是一种富含Ï电子的多功能芳香环系统,已被广泛用于构建机械互锁分子化合物和超分子复合物。现已开发出一种亟需的将其转化为 1-苄氧基-5-羟基萘的程序。它包括:(i) 1,5-二羟基萘的双乙酰化,(ii) 还原性去除两个乙酰基中的一个,(iii) 苄基化,(iv) 裂解剩余的乙酰基。
