A synthesis of substituted 1,4-benzoxazepin-3-one is described starting from salicylaldehyde, aniline and chloroacetyl chloride. Use of 2-bromo-3-phenylpropionyl chloride gave access to 2-benzyl-1,4-benzoxazepin-3-one; an addition/elimination sequence afforded the corresponding benzylidene derivative which structure has been confirmed by an X-Ray analysis. Biphenyl substituents were also introduced in position -4 of this scaffold.
