Multi-membered O,N,S-heterocyclesR 0692 Microwave-Assisted Three Component One-Pot Synthesis of Pyrimido-Ox-

azepines. — A flexible approach to pyrimido[4,5-b][1,4]benzoxazepin-4-ones is de-scribed. The speed of microwave chemistry allows fast processes without transfer of the reaction mixture and work-up of the intermediates. — (HUDSON, C.; MURTHY, V. S.; ESTEP, K.
