| Outline of Final Research Achievements |
We have developed copper-catalyzed regio-and stereoselective aminoborations of alkenes by using an electrophilic amination as a key step. Under optimal conditions, electronically activated styrenes as well as strained methylenecyclopropanes and bicyclic alkenes could be employed. Additionally, we successfully found an efficient Cu-based catalyst system for the challenging unactivated terminal alkenes, which are know to be feedstock materials. The obtained aminoboration products can be useful intermediates in organic synthesis because the resulting boron functionality can be a versatile synthetic handle for further transformation. Additionally, related regio- and enantioselective hydroamination catalysis was also developed.
