Atropselektive Synthese axial‐chiraler Biaryle

Abstract: Eine rotationsgehinderte und dadurch stereogene Biarylachse ist das strukturell und stereochemisch entscheidende Element einer ständig wachsenden Zahl von Naturstoffen, chiralen Auxiliaren und Katalysatoren. Daher ist es nicht überraschend, dass im letzten Jahrzehnt bedeutende Fortschritte in der asymmetrischen Synthese axial‐chiraler Biaryle erzielt worden sind. Neben dem klassischen Zugangsweg, der direkten Aryl‐Aryl‐Kupplung, sind innovative Konzepte entwickelt worden, in denen die asymmetrische Information… Show more

“…The latter aspect is of particular importance, since there is a high demand, but no general solution, for enantioselective phenol coupling in organic synthesis, even though some promising approaches exist. [13] We present herein the cloning, expression, purification, and functional characterization of a DP from Arabidopsis thaliana, which mediates the laccase-catalyzed enantioselective oxidative phenol coupling of 1 to (À)-2. We further show that the enantioselectivity of the newly characterized Arabidopsis DP is opposed to that of the known Forsythia DP.…”

“…Der zweite Aspekt ist umso wichtiger, da es für enantioselektive Phenolkupplungen zwar einen großen Bedarf, bislang aber trotz einiger leistungsfähiger Ansätze keine allgemeine Lösung gibt. [13] Wir stellen hier die Klonierung, Expression, Reinigung und funktionelle Charakterisierung eines DP aus Arabidopsis thaliana vor, das die Laccase-katalysierte enantioselektive oxidative Kupplung von 1 zu (À)-2 ermöglicht. Weiterhin zeigen wir, dass die Enantioselektivität des hier charakterisierten DP aus Arabidopsis zu der des bekannten DP aus Forsythie entgegengesetzt ist.…”

“…[1,2] Biaryls and their heteroaromatic analogues are some of the most attractive structural units in natural products, bioactive compounds, photonic materials, functional polymers, ligands in catalysts, and theoretically interesting molecules. [3] For aryl-aryl bond formation, transition metal-mediated coupling has been employed in most cases.…”
