Participation by the nitro-group in the ring-opening reactions of substituted o-nitrophnylethylene oxides
Abstract
Ethereal hydrogen chloride converts substituted o-nitrophenylethylene oxides into products identified as tautomeric 3,4-dihydro-1,3-dihydroxy-4-oxoquinoline derivatives: a course for these reactions involving participation by the nitro-group in the acid-catalysed opening of the epoxide ring is discussed.
