In this letter, we developed a palladium-catalyzed procedure for the cyclocarbonylation of propargyl amines. Benzene-1,3,5-triyl triformate (TFBen) has been explored as the CO source and also as the key promotor. Various substituted 2-oxo-dihydropyrroles were produced in a facile manner in good yields (up to 90%).
A palladium‐catalyzed double carbonylation of propargyl amines and benzyl chlorides employing benzene‐1,3,5‐triyl triformate (TFBen) as the CO source has been developed. By using this protocol, various 1,5‐dihydro‐2H‐pyrrol‐2‐ones were produced in good yields.

An effective Ag(I)-mediated annulation of 2-(2-enynyl)pyridines and propargyl amines was developed, unexpectedly affording a broad range of functionalized 1-(2H-pyrrol-3-yl)indolizines in moderate to excellent yields. The developed method is characterized by operational simplicity, ready availability of starting materials, high regioselectivity, and broad substrate scope under mild reaction conditions
