Synthesis of 1,4-Oxazepin-7-ones Using Baylis-Hillman Products as Key Intermediates­

Zusammenfassung

Baylis-Hilman adducts derived from aromatic aldehydes and methyl acrylate can be readily converted to 1,4-oxazepin-7- ones substituted in 2-, 3-, or 4-position by condensation with amino alcohols.
