The development of robust and efficient strategies to access structurallydiverse drug‐like compound collections remains an important challenge for small molecule probe development and drug discovery. Following a build/couple/pair strategy we have established bidirectional approach to unprecedented benzoxazepines by employing a Pictet–Spengler/aza‐Michael addition cascade and Schiff base/aza‐Michael
