Indium(III)-Catalyzed Synthesis of Benzo[b]furans by Intramolecular Hydroalkoxylation of ortho-Alkynylphenols: Scope and Mechanistic Insights
(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(III) as π-acid Catalyst for the Electrophilic Activation of Carbon–Carbon Unsaturated Systems
(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-Catalyzed Synthesis of Benzannulated Spiroketals by Intramolecular Double Hydroalkoxylation of Ortho-(Hydroxyalkynyl)Benzyl Alcohols
(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
(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, ... -
Synthesis of D–A–A and D–A–D Pyrimidine π-Systems Using Triorganoindium Reagents: Optical, Vibrational, and Electrochemical Studies
(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 ...
