On May 31, 1987, Cottet, F.; Cottier, L.; Descotes, G. published an article.Computed Properties of 42900-89-0 The title of the article was New syntheses of isochromene. And the article contained the following:

Isochromene (I) was synthesized in 3 steps from homophthalic acid (II) as well as from 2-indanone (III). Esterification of II, followed by selective reduction with diisobutylaluminum hydride gave 52% 3-hydroxyisochroman (IV). IV was also obtained by Baeyer-Villiger oxidation of III with m-chloroperbenzoic acid to 3-isochromanone and subsequent reduction with diisobutylaluminum hydride. IV was dehydrated to I by distillation in the presence of KHSO4 in a total yield of 48% from II and 69% from III. The experimental process involved the reaction of Isochroman-3-ol(cas: 42900-89-0).Computed Properties of 42900-89-0
