title: The development of efficient protocols for the palladium-catalyzed cyclization reactions of secondary amides and carbamates.
abstract: [formula: see text] With the proper choice of palladium catalyst, ligand, and base, five-, six-, and seven-membered rings are formed efficiently from secondary amide or secondary carbamate precursors, offering significant improvements to currently existing methodology.
