脒类化合物属于含氮化合物, 具有非常重要的生理活性. 利用稀土配合物催化合成环状脒类化合物的报道不多见. 以未活化的烯腈与脂肪族胺为原料, 简单的三烷基稀土金属配合物Y(CH2C6H4NMe2-o)3为预催化剂, 发生N—H键对CN与“C=C”的插入串联反应, 合成了一系列环状脒类化合物, 产率22%~96%. 该方法具有催化剂简单、反应条件温和、原子利用率百分之百的特点, 为环脒的构建提供了一种新途径.

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
