Journal ArticleDOI
Trans-selective asymmetric aziridination of diazoacetamides and N-Boc imines catalyzed by axially chiral dicarboxylic acid.
TL;DR: Axially chiral dicarboxylic acid (R)-1d catalyzed reaction of diazoacetamides and N-Boc imines provided a novel organocatalytic means for the formation of enantiomerically enriched N- Boc protected trans aziridines.
Journal ArticleDOI
Catalytic Asymmetric Alkynylation of C1‐Substituted C,N‐Cyclic Azomethine Imines by CuI/Chiral Brønsted Acid Co‐Catalyst
TL;DR: The exploration of the alkynylation as a novel direct catalytic asymmetric method to provide a variety of chiral C1-alkynyl tetrahydroisoquinolines and the addition of an axially chiral dicarboxylic acid, originally developed in this laboratory, as a key co-catalyst is reported.
Journal ArticleDOI
New, chiral phase transfer catalysts for effecting asymmetric conjugate additions of alpha-alkyl-alpha-cyanoacetates to acetylenic esters.
TL;DR: A new, chiral phase transfer catalyst has been designed for the development of a general and useful procedure on the hitherto unknown, asymmetric conjugate additions of α-substituted-α-cyanoacetates to acetylenic esters with high enantioselectivity and moderate E/Z selectivity.
Journal ArticleDOI
Metal-Free CH Bond Activation of Branched Aldehydes with a Hypervalent Iodine(III) Catalyst under Visible-Light Photolysis: Successful Trapping with Electron-Deficient Olefins
TL;DR: Use of a hypervalent iodine(III) catalyst under visible light photolysis allows a mild way of generating acyl radicals from various branched aldehydes, thereby giving the corresponding hydroacylated products almost exclusively.
Journal ArticleDOI
Chiral bifunctional phase transfer catalysts for asymmetric fluorination of β-keto esters
TL;DR: Chiral bifunctional phase transfer catalysts introducing bis(diarylhydroxymethyl) substituents at 3,3'-positions of the chiral binaphthyl core were successfully applied to asymmetric fluorination of cyclic beta-keto esters with high enantioselectivities.
