Enantiospecific Synthesis of ortho ‐Substituted 1,1‐Diarylalkanes by a 1,2‐Metalate Rearrangement/ anti ‐S N 2′ Elimination/Rearomatizing Allylic Suzuki–Miyaura Reaction Sequence

Autor: Raphael Bigler, Beatrice S. L. Collins, Varinder K. Aggarwal, Adam Noble, Belén Rubial, Stefan Aichhorn

Publikováno v: Angewandte Chemie International Edition. 58:1366-1370

The one-pot sequential coupling of benzylamines, boronic esters, and aryl iodides has been investigated. In the presence of an N-activator, the boronate complex formed from an ortho-lithiated benzylamine and a boronic ester undergoes stereospecific 1

Observation of High-Valent Manganese(V)–Corrole Complexes During Metalation of meso-Functionalized A3-Corroles under Aerobic Conditions

Autor: Felix Faschinger, Wolfgang Schöfberger, Armin Sebastian Guntner, Stefan Aichhorn, Stefan Müllegger

Publikováno v: Synlett. 26:2180-2184

We report the synthesis of alkoxy-functionalized Mn(III)–A3-corrole and Mn(V)–corrole complexes. Depending on the length of the alkoxy chain attached to the meso-tetrafluoropenyl moiety, the oxidation state of the central manganese ion could eith

Synthesis of quinoxalines or quinolin-8-amines from N-propargyl aniline derivatives employing tin and indium chlorides

Autor: Stefan Aichhorn, Markus Himmelsbach, Wolfgang Schöfberger

Publikováno v: Organic & Biomolecular Chemistry. 13:9373-9380

Pyrazino compounds such as quinoxalines are 1,4-diazines with widespread occurrence in nature. Quinolin-8-amines are isomerically related and valuable scaffolds in organic synthesis. Herein, we present intramolecular main group metal Lewis acid catal

Bismuth A3-Corroles: Useful Precursors for the Development of meso-Substituted Free-Base Corroles

Autor: Felix Faschinger, Wolfgang Schoefberger, Stefan Aichhorn, Markus Himmelsbach

Publikováno v: Synthesis. 46:3085-3096

Systematic studies on regioselective functionalization reactions employing oxygen-, nitrogen-, and sulfur-containing nucleophiles with bismuth A3-corroles under the influence of a strong non-nucleophilic base are reported. In the case of the thiols a

Scope and limitations of diastereoselective aziridination reactions using stabilised ammonium ylides or α-bromo carbonyl nucleophiles

Autor: Stefan Aichhorn, Michael Reisinger, Mario Waser, Guddeangadi N. Gururaja

Publikováno v: RSC Advances. 3:4552

The applicability of easily available ammonium salts to access aziridines via an ammonium ylide pathway was carefully investigated and compared with classical aza-Darzens approaches using α-bromo carbonyl nucleophiles. Whereas amide-stabilised ammon
