Regioselective Palladium-Catalyzed Heterocyclization–Sonogashira Coupling Cascades from 2-Alkynylbenzamides and Terminal Alkynes: Experimental and DFT Studies

Autor: Belén Vaz, Francisco Cruz, Youssef Madich, Rosana Alvarez, Jose M. Aurrecoechea, Aitor Ortega, Unai Vilar

Publikováno v: Organometallics. 37:3813-3826

A regioselective heterocyclization–Sonogashira coupling cascade between 2-alkynylbenzamides and terminal alkynes is described. The reaction proceeds under Pd(II) catalysis, with air used as a terminal oxidant to regenerate the catalyst from the Pd(

The Pd-catalyzed allylation of 3-acetyl-2-oxindoles with allyl alcohol is performed using 3 mol% of Pd(dba)2, rac-BINAP and BINOL phosphoric acid as catalytic mixture. This procedure allows the in situ synthesis of 3-allyl-2-oxindole by adding Triton

The decarboxylative coupling of carboxylic acids has numerous applications in photoredox catalysis.(1) In these reactions, monoelectronic oxidation of carboxylate anions, followed by carbon dioxide evolution from the so formed RCOO•, gave entry to

Synthesis of 3-substituted 3-fluoro-2-oxindoles by deacylative alkylation

Autor: José M. Sansano, Aitor Ortega-Martínez, Cynthia Molina, Carmen Nájera

Publikováno v: Organicbiomolecular chemistry. 17(3)

The fluorination of 3-acetyl-2-oxindoles with N-fluorobenzenesulfonimide under Lewis acid catalysis using Mg(ClO4)2 gives the starting compounds 3-acetyl-3-fluoro-2-oxindoles. These compounds are subjected to base-promoted deacylative alkylation (DaA
