Let¡¯s face it, organic chemistry can seem difficult to learn, Category: naphthyridines, Especially from a beginner¡¯s point of view. Like 39156-41-7, Name is 4-Methoxybenzene-1,3-diamine sulfate, molecular formula is C8H7FO2, belongs to indole-building-block compound. In a document, author is Golec, Barbara, introducing its new discovery.
Photoinduced oxidation of an indole derivative: 2-(1 ‘ H-indol-2 ‘-yl)-[1,5]naphthyridine
The UV-induced oxidation of 2-(1 ‘ H-indol-2 ‘-yl)-[1,5]naphthyridine acetonitrile solution in the presence of air leads to the formation of 2-(1,5-naphthyridin-2-yl)-4H-3,1-benzoxazin-4-one as a major product and N-(2-formylphenyl)-1,5-naphthyridine-2-carboxamide as a minor one. The probable reaction mechanisms are different for the two photoproducts and may involve both the reaction with singlet oxygen generated by the excited substrate or the reaction of the excited substrate with the ground state oxygen molecule. Electronic absorption and IR spectra indicate that both photoproducts are formed as mixtures of syn and anti-rotameric forms. The obtained results indicate an efficient and easy method for the synthesis of molecules with a benzoxazinone structure.
