Cu(I)-Catalyzed Cycloguanidination of Olefins

This paper describes a novel cycloguanidination process using CuCl as catalyst and diaziridinimines as the nitrogen source. A variety of
conjugated dienes, trienes, and terminal olefins can be effectively diaminated under mild reaction conditions. For dienes and trienes, the
reaction occurs at the terminal double bond with high regioselectivity.
