Pd-catalyzed site-selective C(sp2)–H radical acylation of phenylalanine containing peptides with aldehydes
(Royal Society of Chemistry, 2019-10-14)
The site-selective functionalization of C-H bonds within a peptide framework remains a challenging task of prime synthetic importance. Herein, the first Pd-catalyzed delta-C(sp(2))-H acylation of Phe containing peptides ...
Metal-Catalyzed C(sp2)−H Functionalization Processes of Phenylalanine- and Tyrosine-Containing Peptides
(Wiley, 2021-08-06)
The site-selective chemical diversification of biomolecules constitutes an unmet challenge of capital importance within medicinal chemistry and chemical biology. The functionalization of otherwise unreactive C-H bonds holds ...
Sustainable C–H Functionalization within Peptide & Heterocyclic Chemistry
(2020-11-10)
Chemistry is known to play a crucial role in the universal commitment to achieve sustainable methodologies in which the reduction of energy consumption and the production of waste constitute great challenges for the ...
Novel studies on enamine and acid organocatalysis on carbon-carbon bond forming reactions
(2016-03-11)
Los cicloaductos derivados de prolina no naturales densamente funcionalizados NO2-XL-OMe 5aa y NO2 NL-OMe 5aa poseen un gran interés en los campos de la química y biología ya que pueden complementar a los aminoácidos ...
Chiral gold(I) vs chiral silver complexes as catalysts for the enantioselective synthesis of the second generation GSK-hepatitis C virus inhibitor
(Beilstein Institut, 2011-07)
The synthesis of a GSK 2(nd) generation inhibitor of the hepatitis C virus, by enantioselective 1,3-dipolar cycloaddition between a leucine derived iminoester and tert-butyl acrylate, was studied. The comparison between ...
Synthetic scope and DFT analysis of the chiral binap-gold(I) complex-catalyzed 1,3-dipolar cycloaddition of azlactones with alkenes
(Beilstein Institut, 2013-11)
he 1,3-dipolar cycloaddition between glycine-derived azlactones with maleimides is efficiently catalyzed by the dimeric chiral complex [(S-a)-Binap.AuTFA](2). The alanine-derived oxazolone only reacts with tert-butyl ...
Cross-Dehydrogenative Coupling Reactions for the Functionalization of α-Amino Acid Derivatives and Peptides
(Georg Thieme Verlag, 2018-06-25)
The functionalization of typically unreactive C(sp3)–H bondsholds great promise for reducing the reliance on existing functionalgroups while improving atom-economy and energy efficiency. As a re-sult, this topic ...
Iron-Catalyzed C(sp3)−H Functionalization of N,N-Dimethylanilines with Isocyanides
(Royal Society of Chemistry, 2018-01-22)
An efficient ligand-free Fe-catalyzed oxidative Ugi-type reaction toward the assembly of α-amino amides and short peptides is described. The reaction proceeds through the α-C(sp3)−H oxidation of N,N-dimethylanilines and ...
Site-Selective Cu-Catalyzed Alkylation of α-Amino Acids and Peptides toward the Assembly of Quaternary Centers
(Wiley, 2018-10-15)
The Cu(I)-catalyzed selective a-alkylation of a-amino acid and peptide derivatives with 2-alkyl-1,3-dioxolanes is reported. This oxidative coupling is distinguished by its site-specificity, high diastereoselectivity, and ...
Cu-Catalyzed Site-Selective C(sp2)–H Radical Trifluoromethylation of Tryptophan Containing Peptides
(ACS Publications, 2020-02-13)
Site-selective functionalization of C–H bonds within a peptide framework poses a challenging task of paramount synthetic relevance. Herein, we report an operationally simple C(sp2)–H trifluoromethylation of tryptophan ...
