In an article, published in an article, once mentioned the application of 39648-67-4, Name is (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide,molecular formula is C20H13O4P, is a conventional compound. this article was the specific content is as follows.Quality Control of: (R)-4-Hydroxydinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepine 4-oxide
An efficient Rh(II) carboxylate and Bronsted acid catalyzed direct pi-extension of indoles to 4-substituted carbazoles is developed. The reaction involves a regioselective C-3 functionalization of indole by a rhodium enalcarbenoid and a Bronsted acid assisted cyclocondensation. In addition a twofold regioselective pi-extension of pyrroles to 4,8-disubstituted carbazoles has also been developed. The utility of the methodology was demonstrated with the synthesis of analogues of an hepatitis C virus replication inhibitor and a secreted phospholipase A2 (sPLA2) inhibitor.
