3,3‐Disubstituted oxindoles were divergently synthesized by diastereoselective transformations including nucleophilic addition, alkylation, and cycloaddition using common, axially chiral N‐aryl oxindoles. Notably, high diastereoselectivities (up to >95:5) were observed with ortho‐monosubstituted N‐aryl oxindoles to give various oxindole scaffolds, and facile removal of the p‐(benzyloxy)aryl moiety

environmental-benign compound prepared from CO2, shows diverse reactivity. In this communication, a palladium-catalyzed Intramolecular carbopalladation and Carbonylation has been explored for the synthesis of functionalized isoquinoline-1,3-diones and oxindoles by using DMC as both green solvent and reactant. Moreover, formic acid is employed as the CO source in this reaction.

Diastereoselective synthesis of 3,3-disubstituted oxindoles from atropisomeric N-aryl oxindole derivatives
Diastereoselectivesynthesis of 3,3-disubstituted oxindoles has been examined by transformations involving nucleophilic addition, alkylation, and cycloaddition using chiral racemic N-aryl oxindoles bearing C–N axial chirality. The most striking features of this approach are high diastereoselectivities (up to >95:<5) when using ortho-monosubstituted N-aryl oxindoles and easy removal of the p-(benzyloxy)aryl
