Atropo-enantioselective biaryl synthesis by stereocontrolled cleavage of configuratively labile lactone-bridged precursors using chiral H-nucleophiles
Gerhard Bringmann,Thomas Hartung +1 more
TL;DR: The atropo-enantioselective synthesis of axially stereogenic, sterically shielded biaryl systems is described, by stereocontrolled ring opening of the corresponding lactone-bridged, still configurationally labile precursors.
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
Erste atrop‐enantioselektive Ringöffnung achiraler Lacton‐verbrückter Biaryle mit chiralen Boranabgeleiteten Hydridübertragungsreagentien
Gerhard Bringmann,Thomas Hartung +1 more
Journal ArticleDOI
Novel Concepts in Directed Biaryl Synthesis, XVI. Synthesis and Structure of Benzonaphthopyrans; Helically Distorted, Bridged Biaryls with Different Steric Hindrance at the Axis
Gerhard Bringmann,Thomas Hartung,Lothar Göbel,O. Schupp,Karl Peters,Hans Georg von Schnering +5 more
TL;DR: In this paper, a simple two-step synthesis of a series of ether-type bridged biaryls, as favorable models for studies of helimerization processes, is described, starting from the known corresponding lactones 1, a variety of differently substituted representatives 3 is prepared, greatly varying by the degree of steric hindrance and thus molecular distortion.
Journal ArticleDOI
Synthesis and absolute stereostructure of dinaphth[2,1- c: 1′,2′-e]oxepin-3-(5H)-one
Gerhard Bringmann,Thomas Hartung,Oliver Kröcher,Klaus-Peter Gulden,Joachim Lange,Hans Burzlaff +5 more
TL;DR: In this paper, the synthesis, enantiomer analysis, and configurational assignment of dinaphth[2,1-c: 1′,2′-e]oxepin-3-(5H)-one, a seven-membered lactone-bridged chiral binaphthalene, is reported.
