Complementary Regioselectivity in the Cu(I)-Catalyzed Diamination of Conjugated Dienes To Form Cyclic Sulfamides

This paper describes the regioselective diamination of conjugated dienes using inexpensive Cup) as catalyst and N,N-di-tert-butylthiadiaziridine 1,1-dioxide as nitrogen source. The regioselectivity of diamination is likely due to dual mechanistic pathways which are greatly influenced by reaction conditions and the nature of the diene. A variety of useful internal and terminal cyclic sulfamides can be obtained in good yield.
