Abstract
Simple and efficient Ga(OTf)3-catalyzed [4+3] cycloaddition of 1,3-diarylpropynones and o-phenylenediamines is developed for the preparation of 2,4-disubstituted-3H-benzo[b][1,4]diazepines. The reaction has advantages of using a green solvent, generating a minimal amount of waste, and easy catalyst recycle.
