Shan, Gang; Flegel, Jana; Li, Houhua; Merten, Christian; Ziegler, Slava; Antonchick, Andrey P.; Waldmann, Herbert published an article about the compound: (R)-5,5′-Bis(diphenylphosphino)-2,2,2′,2′-tetrafluoro-4,4′-bi-1,3-benzodioxole( cas:503538-69-0,SMILESS:FC1(F)OC2=CC=C(P(C3=CC=CC=C3)C4=CC=CC=C4)C(C5=C6OC(F)(F)OC6=CC=C5P(C7=CC=CC=C7)C8=CC=CC=C8)=C2O1 ).Synthetic Route of C38H24F4O4P2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:503538-69-0) through the article.

In the presence of a nonracemic cyclopentenopyridine rhodium complex, O-(arylpentynyl) arylhydroxamates such as I underwent enantioselective C-H activation and cyclization reactions mediated by dibenzoyl peroxide and CsOAc in 2-chloroethanol/1,2-dichloroethane to yield atropisomeric arylisoquinolinones such as II in 45-95% yields and in 78:22-96:4 er. Five of the arylisoquinolinone products (including II) inhibited the Hedgehog pathway in human cells; one of the compounds tested inhibited the Hedgehog pathway but did not displace labeled cyclopamine from Smoothened, implying that at least one of the arylisoquinolinones does not inhibit the Hedgehog pathway through binding to Smoothened.
