  One-Pot Cascade Leading to Direct α-Imidation of Ketones by a Combination of N-Bromosuccinimide and 1,8-Diazabicyclo[5.4.1]undec-7-ene

  摘要：

  A one-pot cascade transformation of ketones into alpha-imidoketones has been developed, in which N-bromosuccinimide (NBS) provides both electrophilic bromine and nucleophilic nitrogen sources, and diazabicyclo[5.4.1]undec-7-ene (DBU) functions as a base and a nucleophilic promoter for the activation of NBS. alpha-Bromination is supposed as the key step in the process, which takes place between more electrophilic bromide active species and enolates.

  Abstract A facile transformation of alkynes into α-amino ketones by an N-bromosuccinimide-mediated one-pot cascade strategy is described. A variety of α-amino ketones are obtained in moderate to good yields under mild conditions. To overcome the multi-step synthesis, N-bromosuccinimide is involved in multiple tasks, playing a key role in the reaction course.
