| 英文摘要 | The aza-michael reaction of a variety of chalcones with weaker nucleophilic carbamates catalyzed by incl3 in the presence of tmscl via the entry of dual activation of both hard nucleophiles (carbamates) and soft electrophiles (enones) to provide the corresponding adducts in good yields. the first example of enantioselective aza-michael reaction of chalcones with carbamates was also investigated in the presence of the present catalyst system.
