Fortschritte bei asymmetrischen Phasentransferkatalysen
TL;DR: In this article, anwendbares Verfahren zur asymmetrischen Synthese wertvoller organischer Verbindungen is proposed, in Kombination mit den vielfaltigen Synthesemoglichkeiten durch Phasentransferkatalysen, ergibt sich so ein universell anwende Verfehlung zu asymmetric synthesis.
Journal ArticleDOI
Enantioselective acylation of secondary alcohols catalyzed by chiral N-heterocyclic carbenes.
TL;DR: The synthetic utility of chiral N-heterocyclic carbenes, which have been used mainly in transition metal-catalyzed reactions as a ligand, was demonstrated by the enantioselective acylation of secondary alcohols.
Journal ArticleDOI
Asymmetric organocatalysis of structurally well-defined chiral quaternary ammonium fluorides
Takashi Ooi,Keiji Maruoka +1 more
TL;DR: Unique organocatalysis of both naturally occurring cinchona alkaloid-derived and purely synthetic chiral quaternary ammonium fluorides in synthetically useful stereoselective bond-forming reactions is overviewed.
Journal ArticleDOI
Designer chiral quaternary ammonium bifluorides as an efficient catalyst for asymmetric nitroaldol reaction of silyl nitronates with aromatic aldehydes
TL;DR: The Designer chiral quaternary ammonium bifluoride 1 method was found to be successfully applicable to other aromatic aldehydes and silyl nitronates, and a high level of anti selectivity and enantiomeric excess was constantly observed.
Journal ArticleDOI
Enantioselective 1,3-Dipolar Cycloaddition Reaction between Diazoacetates and α-Substituted Acroleins: Total Synthesis of Manzacidin A
TL;DR: A titanium BINOLate catalyzed asymmetric 1,3-dipolar cycloaddition reaction between alpha-substituted acroleins and alkyl diazoacetates has been developed and chiral 2-pyrazolines containing a quaternary stereogenic center were obtained in high to excellent enantioselectivities.
