Abstract:

A facile In(OTf)3-catalyzed [3+2+1] annulation reaction between imine units was developed, which represents a novel chemical transformation with imines. In this conversion, 23 kinds of structurally diversified acridine derivatives were rapidly obtained in moderate to excellent yields. This protocol features broad substrate scope and excellent functional groups tolerance, giving a new platform for preparing acridines widely used in the program of photoelectric materials.

Key words: Lewis acid catalyst, Acridine derivative, Imine cyclization
