Indium(III) as π-acid Catalyst for the Electrophilic Activation of Carbon–Carbon Unsaturated Systems
Pérez Sestelo, José; Sarandeses, Luis A.; Martínez, Montserrat; Alonso-Marañón, Lorena (Royal Society of Chemistry (Gran Bretaña), 2018-07-25)[Abstract] This review focuses on the utilization of indium(III) as π-acid for the activation of C–C unsaturated bonds in organic synthesis. In addition to its well-known σ-coordination with carbonyl derivatives, indium(III) ... -
Indium(III)-Catalyzed Synthesis of Benzo[b]furans by Intramolecular Hydroalkoxylation of ortho-Alkynylphenols: Scope and Mechanistic Insights
Alonso-Marañón, Lorena; Martínez, Montserrat; Sarandeses, Luis A.; Gómez Bengoa, Enrique; Pérez Sestelo, José (American Chemical Society (ACS), 2018-06-12)[Abstract] Indium(III) halides catalyze the hydroalkoxylation reaction of ortho-alkynylphenols to afford benzo[b]furans in good yields. The reaction proceeds with 5-endo-dig regioselectivity with a variety of phenols ... -
Indium-Catalyzed Synthesis of Benzannulated Spiroketals by Intramolecular Double Hydroalkoxylation of Ortho-(Hydroxyalkynyl)Benzyl Alcohols
Pérez Guevara, Raquel; Sarandeses, Luis A.; Martínez, Montserrat; Pérez Sestelo, José (Royal Society of Chemistry (Gran Bretaña), 2022-10-31)[Abstract] The novel indium-catalyzed synthesis of benzannulated spiroketals by a double intramolecular hydroalkoxylation reaction of o-(hydroxyalkynyl)benzyl alcohols is reported. The reaction proceeds under mild reaction ... -
Microwave-Assisted Direct Synthesis of BODIPY Dyes and Derivatives
Da Lama Vázquez, Ana; Pérez Sestelo, José; Sarandeses, Luis A.; Martínez, Montserrat (Royal Society of Chemistry (Gran Bretaña), 2022-09-23)[Abstract] A microwave-assisted one-pot synthesis of BODIPY dyes from pyrroles and acyl chlorides is reported. This protocol features short reaction times, low temperatures, minimum amount of solvent, scalability, versatility, ... -
Sequential In-catalyzed intramolecular hydroarylation and Pd-catalyzed cross-coupling reactions using bromopropargyl aryl ethers and amines
Alonso-Marañon, Lorena; Sarandeses, Luis A.; Martínez, Montserrat; Pérez Sestelo, José (Royal Society of Chemistry, 2017)[Abstract] A sequential one-pot indium-catalyzed intramolecular hydroarylation (IMHA) of bromopropargyl aryl ethers and amines, and palladium-catalyzed cross-coupling reaction using triorganoindium reagents (R3In) has been ... -
Synthesis and Structural Analysis of Push-Pull Imidazole-Triazole Based Fluorescent Bifunctional Chemosensor for CU2+ and FE2+ Detection
Da Lama Vázquez, Ana; Pérez Sestelo, José; Valencia, Laura; Esteban-Gómez, David; Sarandeses, Luis A.; Martínez, Montserrat (Elsevier, 2022-07)[Abstract] Fluorescent imidazole-triazole based ligands L1 and L2 have been designed as chemical push-pull chemosensors for divalent metal ions and synthesized through palladium-catalyzed cross-coupling reactions using ... -
Synthesis of D–A–A and D–A–D Pyrimidine π-Systems Using Triorganoindium Reagents: Optical, Vibrational, and Electrochemical Studies
Pérez Caaveiro, Cristina; Moreno Oliva, María; López Navarrete, Juan Teodomiro; Pérez Sestelo, José; Martínez, Montserrat; Sarandeses, Luis A. (American Chemical Society (ACS), 2019-06-26)[Abstract] A series of donor–acceptor–acceptor (D–A–A) and donor–acceptor–donor (D–A–D) systems based on a pyrimidine π-spacer with various substituents at the C-2 position has been successfully prepared. The synthesis ... -
Synthesis of Fused Chromenes by the Indium(III)-Catalyzed Cascade Hydroarylation/Cycloisomerization Reactions of Polyyne-Type Aryl Propargyl Ethers
Alonso-Marañón, Lorena; Sarandeses, Luis A.; Martínez, Montserrat; Pérez Sestelo, José (Royal Society of Chemistry (Gran Bretaña), 2018-06-15)[Abstract] Fused 2H-chromenes are prepared by the cascade hydroarylation/cycloisomerization reactions of polyyne-type aryl propargyl ethers using indium(III) catalysis. The transformation proceeds with 6-endo-dig ...
