Studies on the Chemistry of O,N‐ and S,N‐Containing Heterocycles, 9 1) . ‐ Investigations of the Formation of Pyrido[2,1‐ d ]‐[1,5]benzoxazepines and Pyrido[2,1‐ d ][1,5]benzothiazepines The formation of the pyrido‐anellated heterocycles 1 and 3 has been studied. GC‐MS investigations of the reaction of 2‐aminophenol and 7 with acetone show the stepwise condensation of acetone units. Furthermore, the reaction of 7 with 2‐buta‐none, benzaldehyde, and acetophenone, respectively, has been examined.
