Site-Selective Cu-Catalyzed Alkylation of α-Amino Acids and Peptides toward the Assembly of Quaternary Centers
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 ... -
Site-Selective C–H Amination of Phenol-Containing Biomolecules
Girón Elola, Carlota; Sasiain, Ibon; Sánchez Fernández, Rosalía; Pazos, Elena; Correa Navarro, Arkaitz (American Chemical Society, 2023-06)A C–N bond-forming cross-dehydrogenative coupling of a collection of Tyr-containing peptides and estrogens with heteroarenes is described. This oxidative coupling is distinguished by its scalability, operational simplicity, ... -
Site-Selective Trifluoromethylation Reactions of Oligopeptides
Site-selective chemical modifications that target proteinogenic amino acid residues complement the methods entailing genetic manipulation, thereby allowing straightforward and rapid access to engineered proteins. The ... -
Strain-induced effects in the electronic and spin properties of a monolayer of ferromagnetic GdAg 2
Correa Navarro, Arkaitz ; Xu, B.; Verstraete, M. J.; Vitali, Lucia (Royal Society of Chemistry, 2016)We report on the structural, electronic and magnetic properties of a monolayer of GdAg2, forming a moire pattern on Ag(111). Combining scanning tunneling microscopy and ab initio spin-polarized calculations, we show that ... -
Sustainable C–H Functionalization within Peptide & Heterocyclic Chemistry
Guerrero Azurmendi, Itziar (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 ... -
Triazole-Directed Pd-Catalyzed C(sp2)–H Oxygenation of Arenes and Alkenes
Irastorza Epelde, Aitziber ; Aizpurua Iparraguirre, Jesús María ; Correa Navarro, Arkaitz (ACS Publications, 2016-02-24)Selective Pd-catalyzed C(sp2)–H oxygenation of 4-substituted 1,2,3-triazoles is described. Unlike previous metal-catalyzed C–H functionalization events, which preferentially occur at the activated heterocyclic C–H bond, ...
