Synthetic Route of 39648-67-4, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide, molecular formula is C20H13O4P. In a patent, introducing its new discovery.
A Bronsted acid catalyzed dehydrative arylation of 4-indolylmethanols with indoles has been established, leading to a series of indolyl-substituted triarylmethanes in good to excellent yields (up to 97% yield). In addition, in this Bronsted acid catalyzed dehydration process, the only byproduct was water. Accordingly, this approach can be considered to have high atom economy and to be environmentally friendly. This approach not only provides a useful strategy for the synthesis of structurally diversified indolyl-substituted triarylmethanes, but also represents the first example of a 4-indolylmethanol-involved reaction, which will advance the chemistry of indolylmethanols.
