The cobalt-rhodium heterobimetallic nanoparticle-catalyzed synthesis of oxindoles from 2-alkynylanilines in the presence of carbon monoxide is described.
Stereoselective Synthesis of 3-Alkylideneoxindoles using Tandem Indium-Mediated Carbometallation and Palladium-Catalyzed Cross-Coupling Reactions
the stereoselectivesynthesis of various (E)-, (Z)-, and disubstituted 3-alkylideneoxindoles via radical cyclization reactions were investigated using tandem indium-mediated carbometallation and palladium-catalyzed cross-couplingreactions. The proper combination of substrates and reaction conditions is important for good yields. The key step is the first stereoselective carboindation reaction using
