Abstract

Based on an orthogonal protective group strategy dealing with N-protected hydrazine, we established for the first time a highly efficient synthetic pathway leading to 2,3-benzodiazepine-1,4-dione. Moreover, the versatile reactivities exhibited by this 2,3-benzodiazepine-1,4-dione were evaluated towards both benzylation and amination reactions.
