Book ChapterDOI
Biaryls in nature: a multi-facetted class of stereochemically, biosynthetically, and pharmacologically intriguing secondary metabolites.
Journal ArticleDOI
Atropisomerization Barriers of Configurationally Unstable Biaryl Compounds, Useful Substrates for Atroposelective Conversions to Axially Chiral Biaryls†
Gerhard Bringmann,Markus Heubes,Matthias Breuning,Lothar Göbel,Michael Ochse,and Bernd Schöner,O. Schupp +6 more
TL;DR: In this article, the activation barriers of 2-acyl-2-hydroxy biaryls were determined by dynamic NMR spectroscopy for rapid processes and by HPLC-monitored racemization of enantiomerically enriched material for smaller interconversion rates.
Journal ArticleDOI
Novel Concepts in Directed Biaryl Synthesis, IX. Synthesis and Structure of Benzonaphthopyranones, Useful Bridged Model Precursors for Stereoselective Biaryl Syntheses
Gerhard Bringmann,Thomas Hartung,Lothar Göbel,O. Schupp,Christian L. J. Ewers,Bernd Schöner,Rainer Zagst,Karl Peters,Hans Georg von Schnering,Christian Burschka +9 more
TL;DR: In this paper, a two-step procedure for the preparation of a series of lactone-type bridged biaryls 7 as favorable substrates for subsequent atropisomer-selective ring-opening reactions is described.
Journal ArticleDOI
Yb(OTf)(3)-Catalyzed One-Pot Synthesis of beta-Lactams from Silyl Ketene Thioacetals by a Two- or a Three-Component Reaction.
Journal ArticleDOI
Cis- and trans-isoshinanolone from Dioncophyllum thollonii : absolute configuration of two 'known', wide-spread natural products
Gerhard Bringmann,Miriam Münchbach,Kim Messer,D. Koppler,Manuela Michel,O. Schupp,Matthias Wenzel,Adriaan M. Louis +7 more
TL;DR: A new ruthenium-catalyzed oxidative degradation procedure, related to the well-established stereoanalysis of 1,3-dimethyltetrahydroisoquinolines, was elaborated, which allows to unambiguously attribute the absolute configuration of these natural products.
