    A novel photochromic compound which develops a color of a neutral tint and has high color optical density, high fading speed and excellent durability. The present invention is a chromene compound having an indeno(2,1-f)naphtho(1,2-b)pyran structure as the basic skeleton in which a hetero ring having two hetero atoms including at least one sulfur atom is directly bonded to the 6-position and the 7-position of the indeno(2,1-f)naphtho(1,2-b)pyran structure via the hetero atom like the compound represented by the following formula (18).
    一种新型的光致变色化合物,可呈现出中性色调的颜色,具有高色彩光密度、高褪色速度和极好的耐久性。本发明是一种含有吲哚并[2,1-f]萘并[1,2-b]吡喃结构作为基本骨架的咔喃化合物,其中一个含有至少一个硫原子的杂环直接连接到吲哚并[2,1-f]萘并[1,2-b]吡喃结构的6位和7位上,就像以下式子(18)所表示的化合物。

    A series alpha-hydroxyalkyldithiolanes were reacted with a mixture of triphenylphosphine, diethyl azodicarboxylate and hydrazoic acid to give 2-azido-1,4-dithianes stereoselectively. Reduction of the azido group to an amine resulted in racemisation. (C) 1998 Elsevier Science Ltd. All rights reserved.

    2,3-Dihydro-1,4-dithiins and the isomeric 2-alkylidene-1,4-dithianes were synthesized from 1,2-diketones and alkyl pyruvates by kinetically controlled ring expansion of 2-(1-hydroxyalkyl)-1,3-dithiolanes with p-toluenesulfonyl chloride in pyridine. In addition, 2,3-dihydro-1,4-dithiins, the thermodynamic products, were formed exclusively by using p-toluenesulfonic acid in refluxing benzene. The 2-alkylidene-1,4-dithianes were readily isomerised to the corresponding 2,3-dihydro-1,4-dithiins. Similarly, 2,3-dimethyl-6, 7-dihydro-5H-1,4-dithiepine and (+)-2-methylene-3-methyl-1,4-dithiepane were obtained from 2-[(S)-1-hydroxyethyl]-2-methyl-1,3-dithiane.
