Reaction of o-Aminophenol and p-Benzoquinone in Acetic Acid
The reaction of o-aminophenol and p-benzoquinone in acetic acid yields phenoxazinones 1, 5 and 6, phenoxazine 7, triphenodioxazine 2, ditriphenodioxazine 3 and the phenoxazinonyltriphenodioxazine 4.
The reductive cyclisation of 3-hydroxy-2'-nitrodiphenyl ethers provides a new synthesis of 3H-phenoxazin-3-ones, which should be particularly suitable for the synthesis of actinomycins.
