Lewis Acid-Catalyzed Carbofunctionalization of Uncommon C,N-Diacyliminium Ions: Controlling Regio- and Enantioselectivity

Autor: Alexander Villinger, Mario Frahm, Lisa Marie Gronbach, Dirk Michalik, Malte Brasholz, Alice Voss, Jonas Bresien

Publikováno v: Organic Letters. 23:7834-7838

The tricyclic azepino[1,2-a]indole acetates 7, readily accessible by visible-light-driven catalytic photooxygenation of cyclohepta[b]indoles 1, are convenient precursors to novel and uncommon cyclic C,N-diacyliminium ions 3. We report here the first

Value-added chemicals from biomass-derived furans: radical functionalisations of 5-chloromethylfurfural (CMF) by metal-free ATRA reactions

Autor: Lisa Marie Gronbach, Daniel Schmidhuber, Julia Rehbein, Rajesh Dasi, Malte Brasholz

Publikováno v: Organic & Biomolecular Chemistry. 19:1626-1631

Biomass-derived 5-chloromethylfurfural (CMF), a congener of the well-known carbohydrate-based platform chemical 5-hydroxymethylfurfural (HMF), can efficiently be functionalised by radical transformations of its benzylic chloromethyl group. We report

Visible‐Light Cascade Photooxygenation of Tetrahydrocarbazoles and Cyclohepta[ b ]indoles: Access to C , N ‐Diacyliminium Ions

Autor: Jonas Bresien, Alice Voss, Frank Hoffmann, Lisa Marie Gronbach, Mario Frahm, Malte Brasholz, Thorsten von Drathen, Alexander Villinger, Felix Lorenz

Publikováno v: Angewandte Chemie (International Ed. in English)

Tetrahydrocarbazoles and perhydrocyclohepta[b]indoles undergo a catalytic cascade singlet oxygenation in alkaline medium, which leads to chiral tricyclic perhydropyrido‐ and perhydroazepino[1,2‐a]indoles in a single operation. These photooxygenat
