Methods for the conversion of 1,4,5-naphthalenetriols into the corresponding monomethoxy diacetates are described. All utilise the formation of peri-bridged intermediates.

mechanophore that produces a permanent merocyaninedye upon mechanochemical activation, in contrast to the reversible product generated photochemically. Experiments suggest that the irreversibility of the mechanically generated merocyanine is due to a unique reaction in which the scission of an ester C–O bond reveals a β-hydroxy ketone that locks the merocyanine through an intramolecular H-bonding interaction
我们报告了一个 2 H -naphtho[1,2- b]吡喃机械载体在机械化学活化时产生永久性部花青染料,与光化学产生的可逆产物相反。实验表明,机械生成的部花青的不可逆性是由于一种独特的反应,其中酯 C-O 键的断裂揭示了 β-羟基酮,该酮通过分子内 H 键相互作用锁定部花青。除了使用溶液相超声处理证明反应性之外,还在固体聚合物材料中实现了永久性部花青生成。用萘并吡喃机械载体实现的永久着色为传感和力记录应用以及受典型比色力探针可逆性限制的基础研究提供了独特的机会。

The synthesis of a permanent open form of a naphthopyran is described for the first time. The open form of the 10-hydroxy-2H-naphtho[1,2-b]pyran, obtained by reaction of 1,8-dihydroxy-naphthalene with 1,1-diphenylprop-2-yn-1-ol under acid catalysis, is stable due to the establishment of an intramolecular hydrogen bond.
