Abstract

5 H-Oxazolo [4, 5-b] phenoxazine (5) was synthesized by the reaction of 3-amino-2- hydroxyphenoxazine hydrochloride (2) with formamide. A series of styryl- oxazolophenoxazines (9) were prepared by condensation of 2-methyl-5-acetyloxazolo [4, 5- b] phenoxazine methiodide (8) with aromatic aldehydes. By contrast, 2-aryl- oxazolophenoxazines (14) were synthesized by reaction of 3-aminophenoxaz-2-one (1) ...
