The synthesis of nicotinic acid derivatives via the base-mediated nitrogen to carbon rearrangement of N-substituted pyridine 2-sulfonamides is reported. This noteworthy isomerisation of the pyridine sulfonamide protecting group has implications for the use of this protecting group in synthesis.
据报道,通过碱介导的氮到N-取代的吡啶2-磺酰胺的碳重排来合成烟酸衍生物。吡啶磺酰胺保护基的这种值得注意的异构化对该合成中使用该保护基有影响。
