    • Catalytic Cyclization of o‐Alkynyl Phenethylamines via Osmacyclopropene Intermediates: Direct Access to Dopaminergic 3‐Benzazepines 

      Álvarez Pérez, Andrea; González Rodríguez, Carlos; García Yebra, Cristina; Varela Carrete, Jesús Ángel; Oñate Rodríguez, Enrique; Esteruelas Rodrigo, Miguel Ángel; Saá Rodríguez, Carlos (Wiley, 2015)
      A novel osmium‐catalyzed cyclization of o‐alkynyl phenethylamines to give 3‐benzazepines is reported. The procedure allows the straightforward preparation of a broad range of dopaminergic 3‐benzazepine derivatives. Mechanistic ...
    • Dihydrobiphenylenes through Ruthenium‐Catalyzed [2+2+2] Cycloadditions of ortho‐Alkenylarylacetylenes with Alkynes 

      García Rubín, Silvia; González Rodríguez, Carlos; García Yebra, Cristina; Varela Carrete, Jesús Ángel; Esteruelas Rodrigo, Miguel Ángel; Saá Rodríguez, Carlos (Wiley, 2014)
      A new synthetic route to dihydrobiphenylenes has been developed. The process involves a mild RuII‐catalyzed [2+2+2] dimerization of ortho‐alkenylarylacetylenes or its more versatile variant, the Ru‐catalyzed [2+2+2] ...
    • Ruthenium-Catalyzed Oxidative Amidation of Alkynes to Amides 

      Álvarez Pérez, Andrea; Esteruelas Rodrigo, Miguel Ángel; Izquierdo, Susana; Varela Carrete, Jesús Ángel; Saá Rodríguez, Carlos (American Chemical Society, 2019)
      Complex CpRuCl(PPh3)2 catalyzes reactions of terminal alkynes with 4-picoline N-oxide and primary and secondary amines to afford the corresponding amides. The reactions occur in chlorinated solvent and aqueous medium, ...
