The Michael Addition

A convenient method for synthesizing 3-amino-1,5-benzodiazepine-2-one via the Michael addition reaction of o-phenylenediamine with dehydroalanine ester derivatives, followed by cyclization, was developed. This simple method was used to obtain a variety of N-substituted 3-amino-1,5-benzodiazepine-2-ones in one pot with good yields.
