Thermally induced cycloisomerization reactions of 1,6-allenynes gives α-methylene-γ-lactams via intramolecular Alder-ene reactions. The mechanism is supported by computational and deuterium labelling studies. This thermal, non-radical method enables the d

Silver(I) carboxylate complexes promote the carboxylative cyclization of allenylmethylamines to afford 5-alkenyl-1,3-oxazolidin-2-ones in 2-propanol. The use of an N-heterocyclic carbene ligand (IPr) under pressurized CO2 is effective in suppre
Iodide-promoted aldiminium ionalkyne cyclizations. A convenient synthesis of substituted tetrahydropyridines and 3-alkylidenepiperidines

Iodide-promoted cyclizations of aldehydes with 4-alkynylamines and 3-alkynylamines provide direct synthetic access to alkylidenepiperidines 4 and tetrahydropyridines 8, respectively.
