The synthesis of a variety of 2-oxindoles bearing an all-carbon quaternary center at the pseudo benzylic position has been achieved via a ‘transition-metal-free’ intramolecular dehydrogenative coupling (IDC). The construction of 2-oxindole moieties was carried out through formation of carbon–carbon bonds using KOt-Bu-catalyzed one pot C-alkylation of β-N-arylamido esters with alkyl halides followed by a dehydrogenative coupling. Experimental evidences indicated toward a radical-mediated path for this reaction.

New Strategy

Phosphonium ylides have shown their synthetic usefulness in important carbon–carbon bond formation processes. Our new strategy employs phosphonium ylides as novel carbyne equivalents and features a new approach for constructing carbon–carbon bonds from alkenes.
