we report that, undermicrowave irradiation, the CeCl3·7H2O/NaI/I2 system is capable of promoting a 5-exo-dig cyclization of propargyl amides with good functional group tolerance. The microwave reactor also provides a more convenient and safer method for heating the reaction. This methodology represents a straightforward CeCl3·7H2O/NaI/I2 promoted cyclization using microwave irradiation to accomplish
