Cyclization of hydrazones of 2-acetyl-1-naphthol and 1-acetyl-2-naphthol with triphosgene. Synthesis of Spiro naphthoxazine dimers.
Cyclization of hydrazones derived from 2-acetyl-1-naphthol and 1-acetyl-2-naphthol with triphosgene gave naphtho[1,2-e]-1,3-oxazines, naphtho[2,1-e]-1,3-oxazines or their spiro dimers depending on the molar ratio of triphosgene used for the cyclization.
