Various achiral and chiral Cu(I) salts have been prepared from mesitylcopper(I) and investigated for the diamination of conjugated olefins with 1,3-di-tert-butyldiaziridinone as nitrogen source. It has been found that copper(I) phosphate has high catalytic activity for the diamination, and encouraging ee's have also been achieved with chiral phosphates as(More)
This paper describes the Cu(I)-catalyzed regioselective diamination of conjugated dienes using di-tert-butyldiaziridinone as nitrogen source. The internal diamination and terminal diamination likely proceed via two mechanistic pathways. Various dienes can be efficiently diaminated at the internal double bonds with high regio- and diasteroselectivity in good(More)
