Abstract
AbstractWe have developed a Ni‐catalyzed cascade cyclization/Negishi‐coupling reaction for the formation of pyrrolidines and pyrrolidinones starting from N‐protected allylamines and acrylamides which contain a redox active ester group. The reaction provides two C−C bonds in a single operation and takes place with both alkylzinc and arylzinc bromides as nucleophiles. Activation of RAE by low valent Ni complexes involving a radical pathway followed by a fast cyclization of intermediate carbon radicals is proposed.
