    • Functionalized thiosemicarbazone ligands and their complexes 

      Reigosa Chamorro, Francisco; Lucio Martínez, Fatima; Fernández Figueiras, Adolfo; Munín Cruz, Paula; Vila Abad, José Manuel; Pereira Lorenzo, María Teresa; Frieiro Gomis, Pablo Juan (MDPI, 2016)
      The purpose of this work is the design, synthesis and characterization of thiosemicarbazone ligands bearing a phenyl boronic acid functionality. The main interest is the synthesis of organopalladium compounds with the ...
    • Gold(I)-Catalyzed Intermolecular Cycloaddition of Allenamides with α,β-Unsaturated Hydrazones: Efficient Access to Highly Substituted Cyclobutanes 

      Bernal Albert, Paloma; Faustino, Hélio; Gimeno, Ana; Asensio, Gregorio; Mascareñas Cid, José Luis; López García, Fernando (American Chemical Society, 2014-11-19)
      α,β-Unsaturated N,N-dialkyl hydrazones undergo a mild [2 + 2] cycloaddition to allenamides when treated with a suitable gold catalyst. The method, which represents the first application of N,N-dialkyl hydrazones in gold ...
    • Iridium(I)-Catalyzed Intramolecular Cycloisomerization of Enynes: Scope and Mechanistic Course 

      Fernández Fernández, David; Rodrigues, Catarina A. B.; Calvelo Souto, Martín; Gulías Costa, Moisés; Mascareñas Cid, José Luis; López García, Fernando (American Chemical Society, 2018-07-10)
      We report an Ir(I)-catalyzed cycloisomerization methodology that provides access to carbocyclic systems bearing exo-alkene moieties from alkynyl-equipped acyclic precursors. The method relies on the C–H activation of ...
    • Metal-catalyzed Cyclizations to Pyran and Oxazine Derivatives 

      Varela Carrete, Jesús Ángel; Saá Rodríguez, Carlos (Thieme, 2016)
      Pyrans are privileged heterocyclic structures found in numerous natural compounds with extraordinary biological activities. The synthesis of these relevant structures has attracted a great deal of attention over the years. ...
    • Rhodium(III)‐Catalyzed Annulation of 2‐Alkenylanilides with Alkynes via C‐H Activation: a Direct Access to 2‐substituted Indolines 

      Font Molins, Marc; Cendón Mariño, Borja; Seoane Fernández, Andrés; Mascareñas Cid, José Luis; Gulías Costa, Moisés (Wiley, 2018-05-04)
      A Rh(III) complex featuring an electron‐deficient η5‐cyclopentadienyl ligand catalyzes an unusual annulation between alkynes and 2‐alkenylanilides, to form synthetically appealing 2‐substituted indolines. Formally, the ...
    • Rhodium-Catalyzed Intramolecular [3+2+2] Cycloadditions between Alkylidenecyclopropanes, Alkynes, and Alkenes 

      Araya, Marisel; Gulías Costa, Moisés; Fernández, Israel; Bhargava, Gaurav; Castedo Expósito, José Luis; Mascareñas Cid, José Luis; López García, Fernando (WILEY-VCH Verlag GmbH, 2014-07-17)
      A Rh-catalyzed intramolecular [3+2+2] cycloaddition is reported. The cycloaddition affords synthetically relevant 5,7,5-fused tricyclic systems of type 2 from readily available dienyne precursors. The transformation takes ...
    • Tandem Long Distance Chain-Walking/Cyclization via RuH2(CO)(PPh3)3/Brønsted Acid Catalysis: Entry to Aromatic Oxazaheterocycles 

      Bernárdez Alfaya, Rodrigo; Suárez Rivero, Jaime; Fañanás Mastral, Martín; Varela Carrete, Jesús Ángel; Saá Rodríguez, Carlos (American Chemical Society, 2016)
      A novel route to 1,3-oxazaheterocycles based on cooperative Ru–H/Brønsted acid catalysis is reported. The use of the commercially available RuH2(CO)(PPh3)3 complex allows for an efficient long distance chain-walking process ...
    • Transition metal catalysis in the mitochondria of living cells 

      Tomás Gamasa, María; Martínez Calvo, Miguel; Rodríguez Couceiro, José; Mascareñas Cid, José Luis (Nature Publishing Group, 2016-09-07)
      The development of transition metal catalysts capable of promoting non-natural transformations within living cells can open significant new avenues in chemical and cell biology. Unfortunately, the complexity of the cell ...
    • Vinyl Ruthenium Carbenes: Valuable Intermediates in Catalysis 

      Padín Santos, Damián; Varela Carrete, Jesús Ángel; Saá Rodríguez, Carlos (Springer, 2017)
      Vinyl ruthenium carbenes are easily prepared from the neutral Ru(II) complex Cp*RuCl(cod) in the presence of functionalized alkynes and diazoalkanes. These intermediates have been proposed for several transformations in ...
