The reaction of 6-bromocyclohepta[<I>b</I>][1,4]benzoxazine (<B>19</B>) and <I>o</I>-aminophenol (<B>3</B>) was studied and compared with that of 3-bromo-2-methoxytropone (<B>2</B>) with <B>3</B>. 14H-[1,4]Benzoxazino[3′,2′:3,4]cyclohepta[1,2-<I>b</I>][1,4]benzoxazine, 10-(<I>o</I>-hydroxyanilino)cyclohepta[<I>b</I>][1,4]benzoxazine (<B>D</B>), 1- and 4-formylphenoxazines and their Schiff bases (<B>C</B> and <B>X</B>) were obtained in very good yields by modifying the conditions of the reaction of <B>19</B> with <B>3</B>. Structures of <B>D</B>, <B>C</B>, and their isomers were determined and the possible reaction pathways for the formation of various products are discussed.
