Enantioselective Organocopper-Catalyzed Hetero Diels-Alder Reaction through
Autor: Ahmet, Yesilcimen, Na-Chuan, Jiang, Felix H, Gottlieb, Masayuki, Wasa
Publikováno v: J Am Chem Soc
We disclose a catalytic method for the enantio- and diastereo-selective union of alkyl ethers and hetero dienes. We demonstrate that a chiral Cu–BOX complex catalyzes the efficient oxidation of ethers into enol ethers in the presence of trityl acet

Publikováno v: Organic & Biomolecular Chemistry. 18:7090-7093
We disclose a method for sequential Conia-ene-type cyclization/Negishi coupling for the union of alkynyl ketones and aryl iodides. This process is promoted through cooperative actions of Lewis acidic B(C6F5)3, ZnI2, Pd-based complex, and a Bronsted b

Enantioselective Conia-Ene-Type Cyclizations of Alkynyl Ketones through Cooperative Action of B(C6F5)3, N-Alkylamine and a Zn-Based Catalyst
Autor: Min Cao, Ahmet Yesilcimen, Masayuki Wasa
Publikováno v: Journal of the American Chemical Society. 141:4199-4203
An efficient and highly enantioselective Conia-ene-type process has been developed. Reactions are catalyzed by a combination of B(C6F5)3, an N-alkylamine and a BOX–ZnI2 complex. Specifically, through cooperative action of B(C6F5)3 and amine, ketone

Direct Conversion of N-Alkylamines to N-Propargylamines Through C–H Activation Promoted by Lewis Acid/Organocopper Catalysis: Application to Late-Stage Functionalization of Bioactive Molecules
Autor: Min Cao, Jessica Z. Chan, Bochao Zhang, Masayuki Wasa, Ahmet Yesilcimen, Yuyang Zhang
Publikováno v: J Am Chem Soc
An efficient catalytic method to convert an α-C-H bond of N-alkylamines into an α-C-alkynyl bond was developed. In the past, such transformations were carried out under oxidative conditions, and the enantioselective variants were confined to tetrah

Publikováno v: Journal of the American Chemical Society. 141(37)
An efficient deuteration process of β-amino C─H bonds in various N-alkylamine-based pharmaceutical compounds has been developed. Catalytic reactions begin with the action of Lewis acidic B(C(6)F(5))(3) and Brønsted basic N-alkylamine, converting
