Abstract

Enamination of a wide various primary amines was successfully carried out in the presence of catalytic amounts of cerium chloride heptahydrate in ionic liquid and solvent-free conditions as 'green' media under mild reaction conditions. ... The β-enaminone compounds are useful precursors for the synthesis of a variety of hetrocycle compounds. [1] They have been used in pharmaceutical, [2] and as building blocks for the synthesis of aminoacids, [3] peptides [4] ...
