Abstract

An efficient and convenient palladium-catalyzed reductive system by employing sodium hydride as the hydrogen donor and acetic anhydride as an activator has been developed for transfer hydrogenation and acetylation of a wide range of N -heteroarenes including quinoline, phthalazine, quinoxaline, phenazine, phenanthridine, and indole. Moreover, acridine substrates could be directly reduced without the use of acetic anhydride. This protocol provides a simple method for the preparation of various saturated N -heterocycles.

Abstract

Troponoid derivatives incorporating imidazolin-2-one moieties were efficiently constructed via a cascade process, under simple thermal conditions, which features a novel nitrogen source, is catalyst- and oxidant-free, and has high atom- and step-economy. [ABSTRACT FROM AUTHOR]
