We report a chiral phosphoric acid-catalyzed asymmetric aza-Friedel–Crafts reaction of newly developed indeno[1,2-b]quinoxalin-11-imines for the efficient synthesis of diverse chiral 11-amino-indeno[1,2-b]quinoxaline derivatives.
In this research, initially a Schiff base compound was synthesized and immobilized on chelated magnetic copper ferrite nanoparticles with a chitosan surface to prepare the CuFe2O4@CS-SB nanocomposite.
Deoxygenation–chlorination of 3a,8b-dihydroxy-4-oxo-indeno[1,2-b]pyrroles by Vilsmeier–Haack reagent.
A novel synthetic route to a trans-fused indeno[1,2-b]indole proceeds via photo-Nazarov cyclization of a 3-acylindole precursor and stereospecific hydride shift at an in situ-formed dioxaphospholane.
Molecules where the first excited singlet state is lower in energy than the first excited triplet state have been discovered which have the potential to revolutionize OLEDs.
