On February 29, 1980, Bird, C. W.; Latif, M. published an article.Synthetic Route of 38939-88-7 The title of the article was A new synthesis of 3H-phenoxazin-3-ones. And the article contained the following:
Nine 3H-phenoxazin-3-ones I (R = H, Me, CO2Me; R1 = H, Me; R2 = H, Me, Cl, CO2Me, OH), potential intermediates in actinomycin synthesis, were prepared by cyclization of the novel nitro ethers II. Thus, II (R = R1 = R2 = H) was treated with Zn dust and NH4Cl in aqueous MeOCH2CH2OMe, and the solution aerated to give 67% I (R = R1 = R2 = H). The aeration is required to reconvert the alc. product of the reduction to I. The experimental process involved the reaction of 2-Chloro-4-methyl-1-nitrobenzene(cas: 38939-88-7).Synthetic Route of 38939-88-7
