title: Direct solvent-free regioselective construction of pyrrolo[1,2-a][1,10]phenanthrolines based on isocyanide-based multicomponent reactions.
abstract: A novel efficient one-pot four-component regioselective synthesis of pyrrolo[1,2-a][1,10]phenanthrolines in excellent yields has been developed by 1,3-dipolar cycloaddition of aldehydes, malononitrile, and isocyanides with 1,10-phenanthroline under solvent-free conditions within 3 min without using any catalyst or activation. The products were preliminarily investigated as chromogenic and fluorescent sensors for Cu(2+) ions.
