Amidines are nitrogen-containing compounds with very important physiological activities. There are few reports on the synthesis of cyclic amidines catalyzed by rare earth complexes. In this paper, a series of cyclic amidines were synthesized by the tandem reaction of N—H to CN and “C=C” with simple trialkyl rare earth metal complex Y(CH2C6H4NMe2-o)3 as precatalyst with 22%~96% yields. The method has the characteristics of simple catalyst, mild reaction conditions and 100% atomic utilization. It provides a new way for the construction of cyclic amidines.

Key words: rare earth metal complexes, tandem reaction, aliphatic amine, amidine, synthesis
