Journal ArticleDOI
A Novel Coupling 1,3-Dipolar Cycloaddition Sequence as a Three-Component Approach to Highly Fluorescent Indolizines
TL;DR: Fluorescence studies with pyridinyl-substituted representatives reveal not only that indolizines and biindolizine derivatives are highly interesting fluorescence dyes but that their fluorescence color can also be reversibly switched upon altering the pH of the medium.
Journal ArticleDOI
Regioselective Formation of Saturated Abnormal NHC–Gold(I) Complexes by [3+2] Cycloaddition of Azomethine Ylides and Isonitrile Gold(I) Complexes
A. Stephen K. Hashmi,Dipl.-Chem. Dominic Riedel,Matthias Rudolph,Frank Rominger,Thomas Oeser +4 more
Journal ArticleDOI
Hexasubstituted donor-acceptor benzenes as nonlinear optically active molecules with multiple charge-transfer transitions.
Boris Traber,J. Jens Wolff,Frank Rominger,Thomas Oeser,Rolf Gleiter,Mark Goebel,Rüdiger Wortmann +6 more
TL;DR: Compound 4 b represents an N LO chromophore with second-order polarisabily among the highest obtained so far for two-dimensional nondipolar NLO chromophores and the peripheral aryl rings in 4 b are less twisted around the connecting bonds than in 3 and 13.
Journal ArticleDOI
Sulfilimines as Versatile Nitrene Transfer Reagents: Facile Access to Diverse Aza‐Heterocycles
Xianhai Tian,Lina Song,Matthias Rudolph,Frank Rominger,Thomas Oeser,A. Stephen K. Hashmi,A. Stephen K. Hashmi +6 more
TL;DR: This study represents a unique gold-catalyzed reaction between alkynes and sulfur ylides, and also includes the first aza-heterocycle synthesis that proceeds by intermolecular nitrene transfer followed by cyclopropanation of the α-imino gold carbenes.
Journal ArticleDOI
Acyl Migration versus Epoxidation in Gold Catalysis: Facile, Switchable, and Atom-Economic Synthesis of Acylindoles and Quinoline Derivatives
Xianhai Tian,Lina Song,Kaveh Farshadfar,Matthias Rudolph,Frank Rominger,Thomas Oeser,Alireza Ariafard,Alireza Ariafard,A. Stephen K. Hashmi +8 more
TL;DR: A switchable synthesis of acylindoles and quinoline derivatives via gold‐catalyzed annulations of anthranils and ynamides via facile in-situ rearrangements is reported.
